I agree with Pointer on this one. Pegging the weight in heavy cover helps get you bait thru the cover efficiently, but no other time
do I peg it.
Something else I discovered . . . I used to fish a 12" worm deep in the summer on a 5/0 - 3/4 oz. football head hook. When the fish
came to the top, they used the weighted hook as leverage to throw it. (They will do the same thing with a big crankbait). Switched to a
traditional T-rig setup, 5/0 hook with a 3/4 oz. bullet sinker (not pegged). Problem solved. The weight slides away from the fish when
they come to the top and that leverage is taken away from them.
