Yes that's it. Jetmaniac has a sweet vid on here done by budproductions showing some great v-wake airs. So does 02vw1.8t
From what I have heard, rolls are much harder on the hull than flips. Slapping the sides takes its toll after a while I guess. Mine's already stressed from the previous owner rolling... Ride it like you stole it! Repair in the winter.
Im trying to hard on my rolls and fail almost every time. I need to get a video of me doing them cause i suck.
