I have an X-7 its a great boat, with a few people in the boat and the factory ballast full the wake is nice. We run 2 350-lbs side ballast bag and get people forward and the wake is plenty big enough. The wake is also easy to adjust. Also with a short rope it is great for beginners and kids.
I ride at 26mph with 80 ft rope and 3 ballast bags and the wake is very good, not an x-star but fun enough. You won't be dissappointed with the X-7.
