Being a live bait fisherman the majority of my life, I had the worst time understanding what a hit was when throwing jigs, creature baits, tx rigged worms etc..
I went to all artificial about 4 years ago I got 2 pieces of advice, and it made me understand....Know what your lure feels like without a fish on it, and when in doubt, set the hook, hook sets are free. Hope that may shed some light, good luck!
