My technique would be slightly different. I'd stay loose on the descent down that chute, weight central, low down, off the brakes, heels dipped, wrists slightly dipped, looking well ahead. Then I'd approach the stump, looking passed it at the landing, extend arms slightly, keeping elbows and knees bent, ready to hit the ramp. Then I'd anchor on the brakes as I reached it, come to a grinding halt and curse a lot. Then I'd head back up to the top of the chute and repeat the above a few times, before riding away cursing my lack of balls.
Glad to have helped.
