The mini-mops are tied on size 10 hooks. The bead heads are on Gamakatsu bonefish hooks and the floating ones are tied on Gamakatsu B10S stinger hooks. The short stubby ones are tied on size 8 hooks, again on the bonefish hooks. the medium size ones are on size 6 bonefish hooks. For some reason I brought 25 packs of each size years ago and it was a chance to use them up. The large ones. The bead heads are tied on a size 4 Allen hook, I want to say a Caddis pupae hook, that I picked up at the last International Fly Fishing show I went to for $2. The floating ones are on size 4 Gamakatsu B10S stinger hooks. The bass ones are or will be tied on Size 2 B10S stinger hook.
