Should be riding with that anyways IMO... but yeah, i busted 4 knee guards last year... one i busted jumping over the road, two I have no idea how i broke, and the last one i hit a drop that was bigger than I thought... moved up to a good pair of knee braces this year and they've already saved my knees from some damage.
...spent a few days this summer welding plastics on the sled from those wrecks...
Not that i know much, but i would recommend a mouth guard too.
On a cornice, I would start with your skis about 2 feet back from the edge and go WFO till your in the air, let off the gas and tap brake as needed. If you want to go bigger start further back, but dont out jump the steep slope of the hill (the farther you go out the flatter your landing, the more chance for hurting yourself)
On a actual rock cliff its a little different you may need to take the time to level off your launching platform. It could prove the difference in success or failure. You may need to start a little further back because the speed needed to get out over the rocks. Again, on the throttle till your in the air then off the throttle and brake as needed.
Take some pictures and let us know how it goes!
