BL setup for a heavy truck?

I've got an E-Maxx that is fairly decked out with RPM parts and other goodies. One of the downfalls is weight. In running form (6 cell batts, EVX, motors, etc) it weighs 13.5 lbs. I know that BL systems can be sensitive to weight.

This is primarily a bashing vehicle, but it does see track time (not to be confused with race time). I need something that has plenty of power, yet little cogging.

Also, I have upgraded to a GorillaMaxx single speed transmission. I've already done up the drivetrain including lightweight tranny gears and CVD's all the way around.

So what's going to be a good system for me?
