setting the fly.
well me and my friend go fishing after school for a few hours at my grandmothers pond on her farm. i usually have good success catching small bass and little sunnies. but as of late i have been haveing troubble setting the hook in the fish mouth. as in today i was fishing for a while and i could see the fish hit the fly but it would never take so after a half hour i switched to a smaller fly with moderate success i cought a few fish but still had the proublm of seeing fish hit and not set. these are small fish to begin with, the bass being aout 6 inches long and the sunnies being 3-4. i was useing a very small hook i'm not familar with hook sizes but i kno it was one of the smaller ones you can get. so what can i do to help set the fly better?
