Cross S1

(18 customer reviews)

The new LOOP Cross S1 fly rod series is the single most important revolution to occur in fly fishing since we introduced the large arbor reel over 20 years ago. It’s that big.

If the large arbor provided revolutionary function that made the fly reel exponentially better, you won’t believe the difference Cross S1 construction makes with fly rods. We could write an entire book on the adventure that has led to the Cross S1 series of fly rods. We could look up and write down all the available superlatives that are yet unused by other manufacturers (not many left nowadays), but the only way to truly describe what we mean is to hand one to you and let you test it for yourself. If there has ever been a time in our history of development of high-performance fly fishing gear where Loop merited a “look” and a test from the fly fishing world, it is now. Over a period of two years we have developed these fly rods where we used the new 3M™ Powerlux™ Composites. The result is amazing, the strength associated with the 3M™ Powerlux™ Composites generates a lightness and controllable elasticity that simply must be experienced.

We have carefully restricted the inherent elasticity of the Loop Cross S1 so that the rod is working evenly over a much wider range than other fly rods. We have managed to make super-strong featherweight fly rods, with an emphasis on fishing where the rod is working with minimum vibration through an entire load range – from close-in and out to even extreme distances. The design requires minimal input power where the rod does the job. It has never been so easy and taken so little effort to deliver precision loops at 10-meters or 30-meters while easily controlling the line or changing the pace of the cast.

Other nano technologies, like carbon nano tubes, cannot filter between carbon fibers due to their higher length-to-width ratio of 15:1. 3M™ Powerlux™ spherical nanoparticles have a 1:1 length-to-width ratio, uniquely allowing for more than 40 percent of nanoparticles to be uniformly dispersed.
FIG. 1 CAPTION: Getting more nanoparticles between each carbon fiber is the key to the performance enhancements of 3M™ Powerlux™ Composites.
FIG. 2 CAPTION: This SEM image shows the rough, three-dimensional surface area that occurs when a 3MTM PowerluxTM Composite is stressed. The exceptional bond between the particle and the resin significantly hinders cracks from spreading. The result: tougher, stronger rods.

3M Company’s Powerlux™ Composites feature a revolutionary technology that transforms how carbon fiber materials perform. This breakthrough is enabled by 3M’s unique ability to formulate resin systems with high concentrations of spherical nano-sized silica particles. Because the particles are so small, they are able to flow between individual filaments of carbon fiber, providing a dense matrix of strength throughout the entire composite. The resulting material enables designers to develop rods that are not only incredibly strong and durable, but also lighter in weight and more sensitive.

Standard composite materials have lower resin stiffness and are prone to cracking or buckling under the stresses a rod sees during a good day of fishing. The more nanoparticles the resin contains, the higher the crack resistance and overall rod toughness. The Powerlux™ composite material contains an astonishing 40 percent of nanoparticles uniformly dispersed and densely packed throughout the resin.

While other companies have reported adding nano technology to their composite materials, none have been successful at adding more than single-digit percentages. Carbon nano tubes, for example, have a high length-to-width ratio of 15:1, so they are not able to disperse uniformly throughout the carbon fibers as shown in figure below.

3M™ Powerlux™ is truly a game changer that bends the rules of carbon fiber composites. The tiny, spherical nanoparticles create such a strong bond between the carbon fibers that rod stress is more evenly dissipated, leading to a significantly stronger, more durable and more flexible rod. By improving strength and sensitivity, 3M™ Powerlux™ gives you performance when it counts.

  1. Peter Schardt

    I have been a user of Sage rods since 1990 and once I put this 5wt cross rod in my hand I could not believe the balance and light tip in my hand. After casting short and long distances it was like having two different rods! Beautiful smooth action with all the power you need. I am getting an 8wt next to update my steelhead rod/Bonefish rod.
    Try this rod and you won’t be disappointed.
    Thanks LOOP!

  2. Luke

    I recently purchased the Cross S1 4wt and immediately fell in love! The black matte finish and the sick wheel seat make for a sexy rod that will be the envy of everyone on the stream. More importantly, this rod casts like a dream! Cast all day, everyday, with pinpoint accuracy beautifully presenting your fly to the most finicky of fish! I highly recommend the Cross S1 and plan on getting one every weight rod that I fish!

  3. Grant Bench

    I’ve been rockin’ the multi reel paired up with the 9′ #4 Cross S1 for over a year now. After a number of days on the water, I can say with confidence that it’s the smoothest 4 weight I’ve ever owned. From large terrestrials to tiny soft hackles fished in the film, this is the rod du jour time and time again.

  4. Ryan benson

    OK……Here is the real skinny on Loop and the Cross S1, the Cross S1 was a miracle and fluke in the making, it has properties no other rod can imitate. It is by far the most smooth but powerful rod I have ever put my hands on! Sage, Scott, Hardy, R.L Winston…..nothing feels the same, do you ever get a feeling if you haul this rod to fast you could possibly break it? Well, fear not with Loop!! It’s 3M technology is so powerfully, smooth, and forgiving at the same time, it’s the ultimate blend for the beginner to advanced angler! Other company’s have 3m tech like hardy and Sage but in all reality it was Loop who got it write with this rod in particular. It’s medium-fast speed so those who love Sage ones…beware…this will overwhelm you. To this day I don’t know how Loop has been such a great secret, but know its time to pay it forward and let people here in California and the USA to wake up…… LOOP!!!!!!

  5. Matthew Benson

    I own the Cross S1 fly rods in the 5 wt, 6wt, 7wt switch and single handed, 8wt flatsman, 10wt flatsman, and 12″ 7wt Spey rod!!!!! I love the action sooooo much, the only thing that comes close to this rod is Sage’s One, and that doesn’t even hold a a stick to the Cross S1!! These are my go to rods first and foremost for their effortless cast, strength, perfect feel and recovery time, and an overall just a unreal made fly rod!! Loop pulled out all the stops when then created the Cross S1!!!!!

  6. Frank Strasheim

    My Flatsman 690-4 rod mixed with my Opti runner has proven to be the perfect marriage. Balanced, powerful smooth and a dream to cast!

  7. Phil

    I’ve been fishing the Cross S1 7 wt (9’6″) for nearly a year now. This rod is by far my favorite rod I’ve even fished… TRUST ME, I have fished a bunch of different rods. All in the past year I have fished the GLoomis NRX, TFO BVK, Sage One, Sage VXP, Sage Method, Orvis Helios, along with many more. This rod, the Cross S1 can’t be beat. I like a rod with POWER, accuracy, and light weight enough to throw all day. This rod is IT for me. If you like throwing streamers, this is your rod. If you like throwing tight loops and distance when you need it, this is your rod. I have landed big browns, bows, pike, tiger muskie, bonefish, and carp on the same Cross S1 7wt. Nuff said. Go cast it…. You will be a believer.

  8. Derek Olthuis

    I am the proud owner of several Cross Rods, these are some tough, tough rods that cast like a laser beam! They have sooo much power and when paired with the right line can blast casts. While traveling through windy Wyoming and fishing big streamers in 30-40 mph winds the rod could still turn over 6″ streamers and throw a line. To say I am impressed is an understatement…. I have caught a lot of fish from Salmon in Ak to Trout in Argentina and Pike/Musky in the states on these rods and they have yet to let me down. I would put the Cross series against any Rod from any manufacturer out there with confidence!

  9. Devan Ence

    I have a number of these rods in my quiver to match any of the situations that I might come across and I have to say that they become my “go to rod” on any river shed. So, if you want a rod that has some backbone and can do anything that you ask of it (nymphing, dry flies, streamers), this is one for you.

  10. Gary Barnes

    i have fished a number of these rods and i have to say that the cross s1 is now my favorite rod of all time. it has performed flawlessly in every fishing condition i have put them in. they are a real workhorse with great castability and sensitivity. try one you won’t regret it.

  11. Chad Kendrick

    The Cross S1 is hands down the best rod I have ever casted/used. It has handled every type of fishing condition I can think to put it through and has come out far in front of the competition. It is the perfect balance of sensitivity and firmness you would look for in your premium go to rod. My 6wt has handled fish so big it had no business being there and came out better then my 8-10wt, at the same time it has handled the most delicate of streams harboring the spookiest of fish that only a 3wt would be suited for. It’s that good, period. Last 6wt I will ever own… Ever!

  12. Jake Forsline

    BUTTER! If I could leave a one word review of this rod, that’d be it. 2 words…. BUTTERY SMOOTH. This holds true for every weight version I’ve been lucky enough to fish. 5wt, 6wt, 9wt, 10wt. Hard to believe any rod could ever feel this light in your hands but be perfectly balanced and incredibly powerful! Get this thing in your hands to try out… But, don’t be shocked when you never feel quite the same about your previous favorite rod.

  13. Kim Nakamura

    I love my Cross S1’s. so far I have the 5wt, 6wt, 8wt, 10wt and as of last week the 6122-6 spey rod. The 6122 for me matched up with a 450 gr Skagit as I swung flies for steelies on the Cowlitz yesterday and fished tips from 10′ of T14 to a type 3. The rod was light in the hand and a great pleasure to cast working small little pockets or reaching out on some of the larger runs. I have it paired with a Classic 79. I am looking forward to fishing this rod on the Ekaluk in August for searun char. I also love my 6wt and use it to cast large streamers on the Yak and it is my go to bonefish rod for my annual Christmas Island trip. All are great tools to make my fishing habit enjoyable.

  14. Don Smith

    This may be the hardest rod to review ever made. You can certainly talk about all the usual stuff like pinpoint accuracy at any distance, near zero lateral movement during the casting stroke (the marketing guys call that “good tracking”), the timed release of kinetic energy generated by the proper mix of composites and resins, you get the picture, because by this point all of us that fish have seen and read all of this and more in every fly rod ad of the last decade (give or take a year). So perhaps the best way to review this rod is from a more philosophical approach, fitting in my mind since LOOP has put 40+ years of true fishing philosophy into this rod, it’s the reason why (unlike other manufacturers who must produce a “new” rod every year, (which most of the time is the same rod with a different color blank and reel seat), LOOP has made this their flagship and stuck with it, and plans to for some time to come. I like what one reviewer said, “It’s like butter”, and it is, even at short distances on heavy rods this thing just feels great and has a buttery smooth tip and casting stroke that lands right where you want it. And then for me there is the “mystical” part of this rod, no matter how hard I try to drive this thing, even double hauling and over exerting the forward stroke, this rod just looks at you and says “Sure, I can do that!” there is some unknown power source in this rod that just never runs out of juice yet at the same time still takes all of that power and produces a light, airy, soft tip, beautiful cast. You feel every inch of flex and get solid, consistent, usable feedback direct to the casting hand no matter what your doing with it, this rod may the first composite stick ever to actually do what a great bamboo rod does in your hand, BECOME PART OF YOU!. That’s what makes this rod so great, its takes everything that’s important and puts it where it matters, THE FISH!!!!

  15. Ron Ratliff

    I guided in Alaska this season. I took two rods with me my Cross S1 flatsman 890 mc/mf and Cross S1 mc/f. They both performed flawlessly when other rods fell short. The 8wt helped me make the long cast needed on a large river swinging hefty flies. When we hooked up it had the backbone needed to pull king salmon out of the current and into the hands of happy anglers!!!!
    The fast 6wt was my go to trout rod, with the large wild rainbows around it was perfect!!!! Multiple large trout were landed throwing large streamers like Dolly lamas, and large sculpen patterns. Agin this rod has backbone, but it is sensitive enough for light tippets. I LOVE my LOOP Rods !!!!!!!

    Looking for the perfect apex predator rod? LOOK NO FURTHER! PERIOD. The Loop Cross S1 in a 10 wt. is my goto rod for musky on the fly. The versatility of this rod can be teamed up with your favorite line; floating, intermediate or sink tip. Casting musky flies all day can be grueling yet while chasing a fish of 10,000 casts make its pleasurable. The power of the Cross S1 will toss all tandem flies, make casting ‘single’ hook flies a breeze, and those heart stopping boat side eats… that musky will not stand a chance!

    Honestly, I cant say enough about the Flatsman in a 11wt…If your stepping up to the fall pursuit of musky, don’t stray too far away from the 11 wt. Have no fear chucking a rod in this wt… Not only does it actually feel like casting with a fly rod and not a over weighted pool cue (like most 11/12wts on the market). This rod will throw all your tandem ‘doubles’ with ease yet is the perfect rod for ‘triples’ or even multi shank flies… and yes I mean the flies that are nearly the length of your forearm! With this rod, the term “Blown Out” from a strong Nort-Eastern (as we call it here in the north woods) at 20 mph winds driving a cold front down from Canada… You want to be out on the water in search of a 50″ fish; there wont be any excuses not to be out there.

    My best catches professionally have been with the Cross S1 rods and Opti Reels!!

    Just picked up a 690-4 Flatsman for calm days and tailing bonefish here in Hawaii. I’ve been casting an 8 wt rod for the last 10 months around Oahu but just could not get a the delicate presentation needed for these spooky bones on calmer days (8 wt is still the go to for windward side blaring winds). The Cross S1 Flatsman is the finest rod I have ever cast and the action is precisely what is needed vs the bigger stiff rods usually associated with salt. The Flatsman 6 wt is perfect with a fighting butt and just enough back bone to get these monsters in while able to slow down and out a stealth shot just in front of a timid veteran cruiser. Bonefish on Hawaii are known to be enormous and very hard to catch but this rod allows me to put perfect shots exactly where I need. I have been fly fishing since I could walk and have owned some nice rods but this is a different level, especially considering the balance the rod has struck between presentation and power. The rod really reminds me of a nice trout rod feel and action but can even put my 8 wt line out nicely (I experimented over lining the rod to see how it would perform with short loads). I think this is due to the nice mid flex that does the work for you. It is obvious that the rod is staying in a nice line because even with all that flex, I put the fly exactly where I aim. The seat looks great and functions really well. I have never put much weight into the convenience of a nice locking seat but this is absolutely the nicest reel seat I have ever used on a rod. It just makes everything smoother during setup and just helps maintain some zen before hitting the water. I cannot say enough about the Cross S1 690-4 Flatsman! I would be interested to compare the 8 wt to my current 8 wt but I can say Loop has hit the sweet spot with the 6 wt version. I highly recommend the 6 wt for flats fishing and I think it would perform just as well on a big river or lake when you need a 6 wt! Loop fan here!
