Bayou Slab Hunter, percher, B&M BOBM, dmann436, Thats all the names I can think of at the moment. These guys fish it or have fished it, maybe they will reply, if not, maybe send them a pm. From what I hear, there are lots of fish there and most of the time it sounds like there are more boats than fish...lol... Your best bet may be to try going during the week when there is alot less pressure on the lake.
