Ron,
Give this a try sometime in the pits. Rig 1 U/L spining rod with 2lbtest, 1/64 oz jig tipped with minnow or crappie nibble. Rig another U/L spinning rod with 4lb test, 1/32 oz jig tipped with minnow or crappie nibble. Use 2 different colored jigs. Cast them out a good cast behind your tube, hold a rod in each hand and start "trolling" with your fins. Vary the speed until you start catching fish. This will change the depth and action of the lures. Don't set the hook. Let the fish hook themselves. You can add some tiny split shot about a foot above the lure if you want to get them a little deeper. I use a Model 110 Hummingbird Fishing Buddy depth finder. It is the cheapest Fishing Buddy made but works fine for this type of fishing. Keep moving until you find an area with fish.

PS I am going to "bump" a post that I made about a "tubers get together". Please post something on the message so I can remember to contact you this spring.
