Berkly makes a florecent colored perch crank bait I've had good luck with in the summer. dives at a perfect angle, and has a bit of a rattle in it. Other then that, dragging crawler harnesses has worked somewhat, and putting a crawler on a plastic fake worm w/ lead head hook and jigging that seems to work sometimes too. Yahoo, thats all my walleye secrets. take em for what there work.
