Nice!!!
Thats what I did the other day. I had been hitting flat water rolls hard, then we saw a barge cruising up the channel and hauled ass. When I got out there, I hit several waves, and rolled every time. I never rode one out though, because I wasn't throwing as fast and tight of a roll. I got a LOT more air, and had time to actually open my eyes and see the horizon spin, which was sick, and then I would crash down on my side and get separated from the ski. I've landed on my side tons of times off flat water attempts, but landing on your side after getting some air threw me for a loop.
Here is one more vid of a flatwater attempt we made the other day. Still 3/4's. I'll land one of these babies SOON.
