Contact Steve David he can tell you all about BTs. You'll need a boat that big on that lake. I would strongly suggest you get a triple motor package of 700s and NXT drives. You never know when you'll have one go down and having 1400hp to get on plane with is a big safety factor on a lake that's known for big water.
Oh and you'll have 20,000lbs to tow so you'll need a medium duty truck.
