I was lying in bed the night before last and an idea popped into my head- I've read Fishing the Dry Fly as a Living Insect, and in that and in other books the flotation of the hook bend is very important since there's more metal. So I was thinking about this and the next day I tied up some dry flies that are hackled at the bend (both parachute and collar-hackle.) The parachute I tied used a scrap of doubled yellow foam as the post for extra flotation.
Basically, the hackle is tied in first, then tails are tied in over the eye, then the body is wound to the tail (any ribbing is tied in near the hackle.)
This gives an added benefit- the body is easier to taper if you start at the front, because dubbing is naturally inclined to be thicker at the top, and you can tie in quills at the base, so they don't break as easily.
Any input? I figured maybe the tippet at the eye would blend in with the tails, but also one concern is that with Catskill-style flies the pull on the back might drown the fly. Could this be fixed with a slack-line cast? I'll have to try it, maybe it'll prevent the tail from going under...
