I have an X-15 and love it. there's a lot of room inside for a boat that size and it handles well. I think the wake is great (IMO, for my riding abilities). it's got a good shape, firm, and big. stock ballast, however can sometimes feel a little inadequate. if you add a little more weight it gets much bigger in size. it also has a great surf wake and it's pretty good with stock ballast and a few people in the boat.
