RE: drop shotting
i basically fish a dropshot like a carolina rig. SLOWLY. its main purpose is to 'suspend' the lure above the bottom, and being able to keep it in the same spot, while still being able to move it slightly.
Ive done a modified dropshot with a crankbait, for spawning beds. I use a heavy ( 1 or 2 oz) weight below a crankbait, cast well beyond the bed until the weight is just at the edge of it, then raise and lower the crankbait in the bed repeatedly.
