I have this boat. Went to the MC factory last fall and test drove/rode behind all of the smaller MC boats (X2, X15, X25, and XStar). The stock wake of the X25 was better than any of those other boats and with the plug-and-play ballast it was nearly perfect.
I like it because with the 2000 pounds of factory ballast (700 hard tanks, 1300 plug-and-play) it throws a huge, clean wake with a very nice lip that kicks me straight up. My kids like it because I can drain all of that ballast and give them a small, clean wake at 18 mph. We just learned how to surf this spring and we're having a blast doing it. Once again, the ballast is completely hidden and fills at the flip of a switch. I thought the rear jump seats were a bit gimmicky at first but we're using them quite a bit when surfing and everyone wants a turn in the "fun seat."
Anyway, to the OP, ask any questions and I'll be glad to answer them.
