I think that fly looks great but ultimately, it's the fish's opinion that matters most!
If they're working, they're good flies, period. Granted, if the fly falls apart after 1 fish...maybe there IS room for improvement.
Keep up the good work!
PS~I get more fish on bead-head PTs than on standard ones. It's my go-to searching pattern. Actually, a bead-headed Prince Nymph is my favorite...but they're fussier to tie. I'll whittle up a dozen or so in the winter, and once used-up during trout season...I'll use something else. lol
