I can do all kinds of inverts on the tramp, w/handle, but when I do the tricks on the water.. I get them around and ride out of them some times, but I 'THROW' the handle. I think the last time I tried to supergrip the handle it felt like it was going to rip my arm off, or it just does'nt feel right to hold on, even when I let up on my carve in.

Try having the driver back off the gas a little while your in the air. You come down on the board with the handle and go, what the hell happened? I still have the handle.
