I have the same boat. We run factory front surf side full, factory rear surf side full, about 400lbs on top of rear factory, taps between 2 and 6 (greater the number = larger wave until it washes out) speed between 10 and 11. I'm 240 6'6" and my wife usually drives (120lbs) and have a kid or two on surf side. That seems to give us the best wave. We are going to experiment with no front ballast this season though. Check out videos of James Walker to see how to generate speed. It seems like he generates most of his speed starting at the peak of the wave, riding it down, then whipping back up. Also check out ragboy's wave and setup. He has a 24V. He basically runs and enzo sac under the surf side seats and locker.
Here are some pics of our wave.
