One thing that works trolling for cutts and bows is a small (Size 4/0) 50/50 dodger (Thats half chrome, half brass) with a black and yellow tube grub tied like a hootchie behind it about 10 inches. Troll that about 1.1 - 1.4 mph on the GPS about 12-15 feet below the surface. Leadcore line is easier and so with that, its 3 colors.

For perch, anchor in about 25 feet of water. Take a heavy sinker (I use 3/8oz on my ultralight setup with 4 lbs test line), slide it on the main line, tie on a swivel, then a short leader (the length of the leader is equal to the amound of line taken up by one turn of the reel handle), then I tie on a small jig (I like 1/32 oz shad darts), tip with a piece of worm and send to the bottom. When the big weight hits the bottom, turn the handle once so its only the jig bouncing bottom. The reason I use a heavy weight is to get the bait past the smaller perch that hang out in shallow depths. The big guys generally hang out near the bottom.
