Books Featuring Rim Chung and His Legendary RS2 Fly

The following books feature Rim Chung, his RS2 fly patter, or variations on the RS2 fly.  Rim, being extremely modest, doesn’t really enjoy any form of self-recognition, but as they say, “imitation is the greatest form of flattery.”

Bob Saile, Trout Country: Reflections on Rivers, Fly Fishing & Related Addictions.  Pruett Publishing Co., Boulder, Colorado 1999.   My favorite quotes or summaries are as follows:

Aside from the Brassie, the most important contribution to the fly boxes of American anglers to come from South Platte lore is the RS-2 —an all-purpose nymph pattern that, depending on size, can resemble the aquatic stages of a midge, a mayfly, or even a caddis.  RS-2 stands for “Rim’s Semblance, Style 2.”  It was born in the tying vice of Rim Chung of Denver, a self-taught fly fisherman who began as a frustrated spin-fisherman.

When Chung came to Colorado from Seoul, South Korea, in 1968, he had a strong desire to catch Colorado trout but only the weakest clues on how to go about it.  He began to fish with spinning tackle but rarely caught anything when he encountered the selective trout of the Platte and other waters.  Two years later, he was ready to give up.  Then a friend suggested he take up fly-fishing.  “What the hell is fly-fishing?” Chung asked his friend.  Chung then began to fish with dry flies, but it was still frustratingly unproductive or, at best, inconsistent.  Finally he met someone who offered to take him nymph fishing.  “What the hell is nymph fishing?” Chung asked.

His progression to becoming a successful trout fisherman was fairly swift after that.  Chung developed his nymphing skills and learned to tie flies.  He decided to try to develop a nymph pattern that was a general suggestion—a semblance—of almost any hatching aquatic insect, depending on size.  What emerged was a pattern that is constructed with a Tiemco 101 hook that has a straight eye, in sizes as big as 14 and as small as 24.  Two strands of microfibers or beaver guard hairs constitute a widely split tail.  The body, or abdomen, is slenderly dubbed beaver fur, either natural gray, or dyed black, olive, or some other color.  A thicker thorax section is also dubbed beaver fur.  The almost directly upright short wing is tied between the thorax and the abdomen on the top side and consists of a clump of gray, webbed saddle hackle fibers, or CDC material, trimmed with scissors into a triangular shape.

Today, the fame of the RS-2 has spread far beyond the South Platte, but it stands as testimony to the ingenuity of the anglers who honed their skills on its challenging currents.

40 Great American Trout Flies by Craig Schuhmann (2016-03-01) Paperback – 1781
by Craig Schuhmann


2008, Streamside Press, Lyons, Colorado.

These are the stories of 34 fly tyers in over 300 pages, perhaps the greatest in the world, including legendary anglers, professional tyers, fly-fishing guides, and writers.  The book focuses on the featured tyers, but it also details, with recipes and color photos, 68 of their favorite fly patterns. Colorado Trout Flies presents a unique and invaluable reference from veteran fly-fishing guide, Todd Hosman who lives near Longmont, Colorado. He is also the author of Fly Fishing Rocky Mountain National Park and Fly Fishing Colorado’s Front Range.

A.K. Best comments on the Colorado Trout Flies  by saying, “Todd Hosman has written a fly tying book like no other. I know some of you may find that hard to believe, but it’s true. Colorado Trout Flies reads like a who’s who of noted Colorado fly tyers and some of the patterns they are known for. But more important, the book contains a short biographical sketch of each tyer that gives the reader some insight on what drove them to create flies that have become local and national standards. Colorado Trout Flies is destined to become a classic not only because of the reasons mentioned above, but also because the fly patterns will fool trout anyplace.”

John Gierach says, “One of my favorite things about this book is that I’m in it, even though I don’t tie professionally and never invented a fly pattern. All I’ve ever done is tinker with flies as I tied them for my own use, now and then coming up with minor changes that either made an existing pattern slightly better or at least didn’t do any real harm. At least at the amateur level, fly tying is like folk music: The songs may be the same, but every banjo picker adds his own licks. That’s why I appreciate Todd’s biographical approach and what I’ll call his sensitivity to the subject (for lack of a better term). A lazier writer would have run through a standard questionnaire with each tyer, filling in the bare facts and quite possibly missing the point. But Todd was smart enough to start fresh each time, asking the single, not so simple question: Who are these people? There’s also a loose thread of community running through the book, although Todd has the good taste notto make more of it than there is. It’s just that some of us who tie flies in Colorado are good friends who have fished together for years, while others are passing acquaintances or are known only by reputation. Some of us have bumped into each other over the years, usually at fly shops, and have made either lasting or fleeting impressions. Flies aren’t tied in a vacuum. There’s a nearly invisible web of cross-pollination that most of us are only vaguely aware of. When I get a new fishing guide-book, I’ll usually look up the rivers I’m familiar with to see of the author got it right, and that’s what I did with Colorado Trout Flies. I read the sections on the tyers I know – some well, others more casually – and Todd invariably nailed them. You don’t just learn about where they came from and how they got into fly tying, you also get a sense of their style, philosophy and humor and of their lives before or outside fly fishing. The conceit in outdoor writing has always been that fishermen are all pretty much the same. The truth is, we’re all pretty much different.”

Rim Chung is featured in the book, as is his RS2 and Plebby.  Originally priced at $69.95, but now available for a lot less, this book is a must have for any serious fly tier or fly fisherman.

The book made me realize how many of my fly fishing friends and acquaintances are truly famous or those that should  be, including Mary Bartholowmew, A.K. Best, John Betts, Jim Cannon, Rim Chung, Charlie Craven, Pat Dorsey, Ed Engle, John Gierach, Ken Iwasama, Shane Stalcup, Rick Takahashi, Gordon Wickstrom, and Coloradoans Mike Bilo, Mike Bostwick, Barry Conyers, Gary Dewey, John Hagen, and a host of my other fishing friends and fly tiers made along the sporting road.

  • Learn to tie 17 popular nymphs, dry flies, and streamers
  • Master fundamental tying techniques in a series of practical lessons Charlie Craven’s Basic Fly Tying is a modern course in fly-tying fundamentals covering the essential tools, materials, and techniques needed to tie a wide range of popular flies. With 1,000 photos, Craven covers cutting-edge techniques for the more tried-and-true classics, such as the Royal Wulff, Adams, and Hare’s Ear, and shares innovative approaches to current patterns such as the Brassie, RS2, and Copper John.
  • Charlie writes, “I use the Black Beauty on a dropper behind a Pheasant Tail or an RS2 much of the time…” in Chapter 7 which features Pat Dorsey’s popular fly also of South Platte fame.  He also repeats this comment in Chapter 10 featuring the Pheasant Tail Nymph, which was originated by Frank Sawyer, but the book features what we now know as the American Pheasant Tail Nymph, as developed by Al Troth.  In Chapter 13 on the Copper John, he also suggests using it with an RS2 dropper, as “I try to match the dropper to the prevailing hatch.”  In Chapters on the Rusty Spinner and the Parachute Blue-Winged Olive, alternate versions are discussed substituting the two-forked tail of the RS2 and Craven writes, “I have noticed no difference in the way the flies float…although [the hackle fiber tail] provides more support than the split tails.  I prefer the split-tailed flies when wade fishing over selective fish that have a bit more time to eyeball my offering, if for no other reason than that I know the split tail is accurate, and I can eliminate that variable from any question of why the fishing wouldn’t eat it.  Sometimes I just like having that in my head.”

  • “The RSII is a great bug with a great profile, and can also be fished as an emerger.  Whenever you throw an RSII or other emerger pattern, concentrate on the swing phase of your drift.  Fish can be induced to eat as the fly rises through the columns.”


Ron Baird

  • “An all-around fly, the RS-2 comes in a variety of colors, and can represent the emerging forms of both midges and blue-winged olives, depending on the color.  Not a few anglers have said if they could only use one fly, it would be an RS-2.


Landon Mayer

  • “…a #18-22 black RS2 are mush-haves on you rig in the heat of summer.”
