The Mono Rig

The Mono Rig is a hybrid system for fishing nymphs (both tight line and indicator styles), streamers, dry-dropper, wets, and small dries. With 20 pound monofilament as a fly line substitute (and with fly-line-style casting) better control, contact and strike detection are gained with the Mono Rig versus a traditional fly line approach.

The Mono Rig is similar to Euro Nymphing and tight line styles, but it’s a full system for fishing all fly types, with and without indicators, with and without split shot.

There are 200+ articles about the Mono Rig on Troutbitten. Listed below are six primary articles that provide the foundation of the Mono Rig concept. Following those, a full list of all the Mono Rig articles with auxiliary material follows.

Fish hard, friends.

Tight Line Nymph Rig

The Mono Rig and Why Fly Line Sucks

For presenting nymphs and streamers to river trout, fly line sucks. There, I said it. Now I have to defend it.

Most underwater deliveries require weight, and using a very long, monofilament leader to cast that weight is more efficient than using fly line; it keeps you in better contact with the flies, and you’ll catch more fish. I’m talking about leaders with butt sections of 20 feet or more . . .

Tight Line Nymphing with an Indicator — A Mono Rig Variant

I dislike arbitrary limits. Placing restrictions on tackle and techniques, when they inhibit my ability to adapt to the fishing conditions, makes no sense to me. I’m bound by no set of rules other than my own. And my philosophy is — Do what works. I guess that’s why I’ve grown into this fishing system. 

Fly Fishing with Streamers on the Mono Rig — More Control and more Contact

If you’re fishing streamers, you’re already well past the original sin in fly fishing. So, rather than fighting with fly line, use the Mono Rig . . .

Hi. I’m a father of two young boys, a husband, author, fly fishing guide and a musician. I fish for wild brown trout in the cool limestone waters of Central Pennsylvania year round. This is my home, and I love it. Friends. Family. And the river.

VIDEO: The Dorsey Yarn Indicator — Our Best and Most Versatile Indy Choice — Building It and Fishing It

For over a decade, my Troutbitten friends and I have fished a small yarn indicator that weighs nothing, is extremely sensitive, versatile, cheap, doesn’t affect the cast, and flat out catches more trout than any other indicator we’ve ever used. What we call “the Dorsey” is a daily-use tool that is integral to our nymphing system. We mount it on a tight line rig or a traditional leader with fly line. It floats like crazy. It signals takes and information about the drift like no other indy we’ve ever used, and it’s an unstoppable fish catcher.

One rod length over and two rod lengths up. That’s the Golden Ratio. That’s the baseline, and it’s where trust in our drift begins. There are surely moments and situations that call for something different. But a good tight line style starts here, within the Golden Ratio of nymphing . . .
