The answer, of course, is yes.
This weekend, I received a question about tying Leisenring’s March Brown Nymph. The reader wanted to know if I thought three pheasant tail fibers for the body was enough. As you can see from my original writeup, I had a few initial questions (or opinions) about the recipe as well. Here’s a little more about my M.O. when I’m tying a pattern for the first time.
I always like to honor the original recipe — at least in the beginning. I want to see what the the tier had in mind, what his or her vision of the pattern was, and perhaps try to figure out what they were trying to accomplish in terms of materials and look. In the case of Leisenring, a giant in the pantheon of American wet fly fishing, respect to the original was surely due. If Big Jim liked the pattern enough to include it in his book, that carried a significant weight. But, even if the pattern creator isn’t on the fly fishing Mount Rushmore, I still like to stick to the original design.
Now, there’s nothing that says you can’t improvise. Indeed, countless patterns have been improved upon because other tyers asked, “what if I?…” So, for example, if there’s a stone fly pattern I’m tying and I think — do I really need that wing case? — I might leave it out after a few iterations. If you’re really curious about discovering the necessity of certain elements or materials, use droppers. Tie one fly according to the original, and then tie one fly your way. Place them on droppers, change the positions frequently to keep it a fair fight, and see if the fish have any preference. Droppers are always the fastest way to find out what the fish want.
I hope this helps. Tie on, ladies and gentlemen.
