My favorite one, the pattern that hooked the fish in my avatar, is to use a #18 caddis or pupa hook. Tie a bit of brown z-lon in at the back of the hook right before it bends towards the point, facing down, not out. Use a sparse olive antron dub over amber brown thread, to just before the eye. Tie in 2 tips of CDC facing straight back parralell with the eye. DEADLY and simple, especially in super smooth water when the fish are just pokin' their noses out.
I'll post images next week.
Tightlines!!!
