I got out the big plug cutter (1/2" dia) and removed a plug from a pair of abandoned foam wedges (think high heel flip flops) after much sanding and stock removal came away with a pretty good looking frog fly. With frogs, I think bass first, then bream but I have been primarily trout fishing lately and was thinking of tying the frog on and using it as a strike indicator for nymph fishing. What are the chances of a trout hitting a frog?
