Mikepet,

Try using a Rapala sallow diving Husky Jerk off trolling boards. These are good for casting or trolling.  This year I have had good luck trolling 3’ and 6’harnesses with meat.  I rig the 6’ with 1oz inline weight off trolling boards and the 6’ on Dipsy Divers.  

As far as boards are concerned I like small boards my favorite is Church Tackle Walleye Boards. The trip mechanism works well and is adjustable.
