Haven't fished Sutton for cats but have wanted to for a long time. I can tell you we electroshocked it for a research study when I was at NC State and there are some BIG (40+ lb.) flatheads in there. Lots of smaller ones too. Hard to go wrong with a live bream on a fishfinder rig for flatheads. Most of the big fish we shocked were in the deeper holes, although that was in early spring so not sure about this time of year. If you have a boat run slow...the lake is slam full of stumps and assorted "structure". Good luck and let us know if you try it!
