I have a 2004 X-2 and surf goofy, and the wake rocks out on the starboard side of the boat! I use a 300lb. under front right seat, KGB, rear 300lb. + 350lb. (in the back).. I run the boat at exactly 9.5 mph, if you go a hair over the wake washes out, Its ALL about the driver to get good wake. also... you should not have to turn the boat in circles, you should be able to go in a straight line the whole time....
