Some flies, notably scuds, hydropsyche, and some other free living
caddis are best imitated with imitations tied on curved hooks, at least
to human eyes. Whether the fish take much notice is a moot point.

My favourite hook for buzzers are size 12 "Sedge" hooks. These have a
lovely curve and do look the part. I believe they fish better as well.
