Having played with draggon flies for a couple of years on warmwater fish a few years ago and eventually came to the conclusion that a gurgler worked as well as anything I came up. Tie it on a #12 hook with an extra long tail, and trim off the bottom hackle.
From those experiments I found that to hook sunfish you need a flexible tail that lets it bend enough to get the hook into the fishes mouth. Other wise lots of hits with ~ 5-10 % hooked. A stinger hook in the tail might work but I always figured it would hook me as often as fish.
