It’s a relatively simple pattern to tie and if you make a variation in color, it loses the isonychia imitation property. That said changing colors to black imitates a stonefly better and a gold as well. Since it’s a basic pattern, you can choose to add flashback or different colors to achieve a different look and feel as desired, but to keep it looking like an iso nymph, you’ll want to stick pretty close to the recipe.
It’s heavy and gets down at the bottom and allows for you to move it up and down through the water column alot by your retrieve. This fly does have a tendency to get hung up a lot and tying a jig-style variation of this fly is also a good idea as the hook point will float upwards helping it to get hung up less.
Isonychia nymphs move around a lot so moving this fly as well as a dead drift is the best way to fish it. Getting a good dead drift and then allowing the fly to skate upwards by just holding still while your fly line drags the fly to the surface is a known and useful technique especially during an ISO hatch.
