The Morrish Hopper - The Origin Story & Lasting Legacy of the Fly that Transformed Fly Fishing

Ken Morrish June 27, 2025

"Tying is food for my soul, and creating something tangible, attractive, and useful gives me a sense of worth that I can't get through a screen or keyboard."

When I was 11 years old, I essentially stepped away from store-bought flies and did my best to tie whatever I needed. It wasn't a deliberate decision, but in hindsight, that's what happened. If I wanted a fly, I tied it. When I had a trip of any size planned, my mind raced with thoughts, often ill-conceived, of what the fish there would want. I would sit down and get to work on my "next great" creation, never following pattern recipes, as being creative came easily to me and was way more fun. Fantasies about how well the flies might work, and the incredible fish that might fall for them, are still very much part of my creative process. Sometimes these extended pre-trip tying jams prove more fun and enriching than the actual trip. Tying is food for my soul, and creating something tangible, attractive, and useful gives me a sense of worth that I can't get through a screen or keyboard. 

As an adult member of society, I am a fairly easy-going, accepting person. I sincerely enjoy and like most people, I'm not horribly caught up in my own opinions, nor fond of hearing myself speak, and I am not snobby or particular when it comes to food, fly rods, or alcohol. But when it comes to critically evaluating flies and how they are designed, I must admit that I'm a bit of a prick. It is the only part of my life in which any type of engineering aptitude emerges, and flaws in form, function, silhouette, and aesthetics jump out at me as though they were illuminated in neon. My fly-tying mentors taught me to be this way before I was a teen, and since there wasn't very much going on in my head back then, it stuck. I am now 58 years old, and I have been tying and scrutinizing flies for 50 years. My critical eye for flies is the cross I bear, and rectifying design shortcomings at the vise each night is one of my greatest sources of purpose and pleasure. These are some of the only problems in today’s unhinged world that I can actually solve, and I really enjoy creating better bugs for myself and anyone else willing to give them a go. 

One day in what might have been 2008, I was fishing, and I caught a grasshopper. I looked at it, long and hard, trying to break it down to its most fundamental attributes. I immediately realized that none of the patterns currently on the market captured the strong angular essence of the creature that was now drooling brown juice onto my hand. Likewise, I had no idea how I would crack the grasshopper code, but I committed to trying. I put the little wriggler in my fly box, and when I unpacked my fishing gear that night, I stuck a pin through the poor thing and stuck it to the cabinet where my tying lamp sat. It remained there, in my immediate sight, for two years, and I would study it almost every night. As a tyer, it was hard to figure out where to start. At that point, no tyers that I was aware of had created long, sharply defined tapers that floated, but that was exactly what was needed. I played with foam endlessly and eventually started laminating multiple layers of it together and then cutting it with long kitchen shears into various shapes. This was the advent of what I call "foam sculpting.” It differed from almost all existing tying methods, as the body was essentially made and laboriously beveled off-vise. Then, with a little slit in the belly and a bit of thread and glue, it was attached, in near-finished form, to the hook. It was unconventional, but it created the defined profile I was after. I fussed with the design and proportions for another six months, always referring to the now dusty, crunchy little fellow pinned to my cabinet. From my sometimes-cynical perspective, one of the pitfalls that affects most fly designers is that they "think" they know what a natural looks like, and they tie accordingly, without critically cross-referencing them or breaking down their most basic silhouette attributes. This hopper was not going to fall into that trap, and in an effort to mimic its angular, almost geometric lines, a new style of tying was created.

Next, I field-tested the flies, and I shared them with others and listened to their feedback, all of which was very positive. Then I set about the dreaded process of tying "perfect" samples in various sizes and colors in the hope that the now-defunct company I designed for would accept the pattern, sell millions of them, and I would become incredibly rich and retire on a private spring creek in New Zealand. Needless to say, that was not what went down. Instead, the company that I shared a great track record with rejected the pattern. They didn't like it and even went so far as to tell me, "Foam is dead." I was not happy and feeling utterly wronged, to put it gently. I kept fishing the hopper, but I stopped designing new patterns for the company in a senseless form of personal protest. Two years passed, at which time I decided to send them the exact same submission of hoppers, in hopes that the decision-makers might have regained their capacity for critical thought and identifying true opportunity. This time my wish was granted. 

In short order, the sales and angling successes of the Morrish Hopper skyrocketed, and within two years, it became by far the best-selling pattern in the company's history. The retirement on the private spring creek never happened, but at least foam was not dead. These days, the Morrish Hopper has been knocked off and modified often, which I do not begrudge and consider a natural part of success in the tying industry that I continue to enjoy. Today, the best-tied and best-priced Morrish Hoppers are produced exclusively by RIO Products. As a Signature Tyer for RIO, anytime you specifically buy a Morrish Series RIO fly from your local fly shop, you just might be getting me a nickel closer to that New Zealand spring creek. They are hand-cut to maintain the strong angles (as opposed to the curved products created with commercially available foam razor cutters), and they have silicone legs that stay strong and supple for multiple seasons. While it was once a radical new fly, it is now a modern classic, available in eight colors and five sizes. My two most-used colors are tan and pink in #8 and #10. Slap one down along your favorite grassy bank this summer and don't be scared to give it a twitch or two. 

Generally, the windier the day the better, but only to a point. If it really starts blowing hard consistently, the hoppers tend to hunker down, and the fishing slows. Warm and gusty conditions are the best, and as a result, afternoon hopper sessions tend to be better than morning sessions. I typically fish on foot rather than from a boat, which is why my favorite rod for fishing the Morrish Hopper is the SAGE 596-4 R8 CORE. I like the extra length to keep my back cast out of the tall grass, and I am a huge fan of the RIO Elite Gold Max fly line. I had a hand in the design process of this line and generally love rear-weighted lines. The Elite Gold Max specifically meets the vast majority of my needs on the water. It roll casts better than any line I've used and kicks hoppers over easily in the wind. If you haven’t fished this fly line, I encourage you to give it a try. While it is marketed as a line for throwing heavy flies and indicator rigs (which it does really well), I see it as an all-around player, in large part due to its long front taper. It has a ton of power; it loads rods quickly and deeply, but its elongated front taper still allows your offerings to land lightly. Personally, if I could only have one RIO floating line for all my trout fishing, this would be it. 

For me, designing flies is a private endeavor but one that is foundational to who and how I am. I need that quiet, creative time to myself, and that is why I tie every night that I am home. My head has always been spinning with ideas for making better bugs, and despite what I think the “next great” creation will be, the fish will ultimately prove to be the only true judges of greatness.
