All I can add is :

if there's a thermocline present, fish above it

take note of the direction you're going when working an area, as sometimes you'll get more hits going one direction than the reverse direction (mrdux seminar note)

don't always make arrow straight runs thru an area, zig zag or run an S pattern ... and watch your inside/outside rods for more hits. Inside rod's baits will be running slower in the turns & outside rod's baits will be going faster, and that can also help tell you the precise speed of the baits that the fish are keying on. (especially when using weights ahead of your cranks ... may not be as much of a factor when pulling cranks w/o added weights)
