Use a free swimming 3 to 4 inch blugill for bait.
The first time DD1 told me this I kinda was like.... yeah right ok.. I put a 3 inch BG on a hook with a bobber about 2 feet up and in about 10 mins or less I had a LMB on!! Hook em just behind the dorsal fin so they can kinda swim natural. And hang on!! lol
A LMB can't stand a struggling fish... he will hammer it if given the chance....
