Greg; Mike G is right I heard from one of my sons co-workers who fishes stillwater a lot and he has taken an 8lber there and has had the line snap on others that were bigger. I believe he uses 10" & 12" worms there. Just pick a spot and hammer it as often as you can!!!! Fish during the low light/ night conditions because these big gals are very shy. We also have a Full Moon comming soon too. (hint) BigBill
