My favorite is a 1/2 oz weight. Followed by a bead. then a swivel. Normally use about 12lb test leader. Topped off with either a pumpkin seed lizard or watermelon red baby brush hog.
When: Summer/Early Fall when the water temps are warm .
Where: On ledges, deep brush, humps, and grass.
Why: The heavier weight can penetrate cover and carolina rig keeps your bait off the bottom for those pesky suspended fish.
