I put a lot of time in on clear water fisheries. One body of water in particular is extremely clear and deep, inhabited by only smallmouth, pickerel, and baitfish. You can see boulders and logs on the bottom in 25' of water. My favorites are usually finesse presentations. Ned rig, wacky/ neko rig, drop shot, shaky head. For hard baits a walking bait and a spybait in natural colors get the most bites for me. Long cats and light line are important, but being stealthy (no splashing/ being noisy, etc.) is importanter.
