A total play off my previous tiger fly tied on a shank with a free flowing hook (which I'm considering swapping out for a treble ala Joe Goodspeed or perhaps a double Gami frog hook). I can't really get the free flowing single to ride appropriately all the time. At any rate, this should solve that problem, but no interchangeable hook.
still in the same ~8" range, but with less weight, should also be easier to cast. Tied up on a 4/0 Ahrex Aberdeen Predator with a touch of foam off the back (top) plus small dumbbell eyes underneath about 1/3 of the way down to create some serious instability yet will also still self correct on the pause. Kinda like a naturally sick/injured baitfish.
