do you have any tips on setting the hook with a frog? Any time a fish comes up to eat it I can't set the hook.

Let him swallow first. Let your line loose. THEN set the hook.

When the moss is thick I always real down after the hit and soon as I feel the fish I set the hook. In open water they tend to obviously get the frog better but either way it's key to wait after that explosion just a couple of secs before setting the hook....sometimes it's hard to do because the excitement and surprise of it makes you just yank...little practice and you'll have it
