Cliff- Its really a decision you have to make, and test drive is the only way to know. Ive wakeboarded behind an 06 Xstar, and the wake is awesome especially when weighted properly. Very big with nice ramp and very solid. However I havent ever surfed it so no comment there. We just got a 2006 VLX, and IMHO I like the interior soooooooo much more on the Malibu, storage however will not be an issue with either boat. Im not an amazing rider(intermediate at most) but the Xstar wake is nice with additional weight, our VLX with MLS(1250lbs) on a 75 foot line at 24.6 is also more than enough weight for 90 percent of the people I ride with, the power wedge will give you a bit extra if you ride with it(I dont). The surf wake on the VLX is amazing, honostly one of the biggest Ive ever ridden, and Ive ridden behind numerous centurions(old boat), Moombas, and Supras. Either boat will be able to give you more than you can handle in the wakeboarding department, it's just going to come down to how you like each aspect of each boat. Demo.
