Sorry about my previous post, Karl. I guess I made the Kaos sound bad. It's actually a very good board(one of the best). Now, if you're getting a good 6 feet of air on every jump, then you might have some problems. That's what I meant by extreme.
They used to put more reinforcement in the boards in order to take that kind of abuse. I think Hydroslide wanted to make the Kaos more affordable for more riders. So they limited the reinforcements to reduce the cost.
