This large Stonefly Nymph is one of my all-time favorites! Dark, heavy, and highly effective, the Atomic Stone consistently brings fish to the net. This pattern is a tricked-out version of Kauffman’s Stone, crafted by Brian Hudspeth, a talented Umpqua Feather Merchants tyer from the Pacific Northwest. While our version has a few slight modifications, it stays true to his original design. The added underbody weight and gills make this pattern a top performer. The time and effort to tie this fly are absolutely worth it! You can tie the Atomic Stone in sizes ranging from 04 to 12, and it’s effective in any waterway where stoneflies are present. While large stoneflies are often thought of as summer nymphs, don’t hesitate to rig one up during the winter months. It’s an excellent lead fly option, helping your rig find depth and enticing opportunistic trout.

I agree that this one will require some serious time at the vise but I’m going to give it a shot. Gathering the materials together and doing a little research, I believe that the original pattern calls for stripped black hackle stems for the antennae. Using biots, as you did, will make them a lot more visible.
