Don't know if anyone out there has heard of these boards, but this Wakesurf is by far the best one I've ever ridden.
They say that you can wakesurf behind even comp. boats with no effort. I tried it in my '90 SunSport with no ballast and no problem, and I love the graphic!
They are from Boulder, CO and have a good thing going... just tryin' to support my CO friends!
