I run the 1,180lbs Gravity Sack in the center locker and the 750's tucked in the rear lockers on my 2006 22 SSV. Great wave and good push with this setup. Supra seem to surf better with more weight in the middle/front. I got tired of filling a 400lb bag for the front and went with the 1180 to replace the stock 650. It allows you to adjust the fill with the amount and size of the people. I just ordered the bags through Wakemakers and ordered extra hose and fittings to extend the rear corner plumbing. The front center was an easy swap out. I removed the rear carpet/board in the front of the rear lockers so the 750's can expand a little better. I usually run the plate up at least 75% and adjust it to clean the wave up the best I can. 10.7 MPH. Just go back from Powell with this set up and everyone was pretty positive about the way the wave has evolved from the stock bags from the beginning. I'm 6'2" 225lbs and ride wireless pretty easy with this wave.
