I use bandit cranks. The deep divers go 8-12 feet and they have a mid range that goes 4-8 feet. Put out 50 to 100 feet of line and troll 1 - 1.5 MPH. If you go too much less than 1 MPH, they won't dive as deep as needed. It is harder to slow troll cranks so it doesn't work as well in the Winter in my opinion.
