If I hook, whether I bring them to hand or not (I imagine some are lost because of barbless hooks I employ), around 75% of the 6-10 inch trout that rise to the dry flies I fish in small mountain streams, I think I've had a good rate of success.

On most days, though, my hook up rate is closer to 50%, and on really bad days drops to 25%.

This topic has probably been discussed, by I couldn't find it with my search.

What's your hook up rate for small trout on dries?
