I'd prefer 6 or 8 feet, but I like to pop an occasional walleye. I hardly ever see a wally at less that 12 fow. So that's what I set up in. Right now I'm in 12 fow and about 8 feet from a 45 degree drop off. Most of the northerns come from this shallower area which is to my back. The walleyes seem to appear from deeper water along with an occasional herring/whitefish.
