We had a 15 foot high spine, and we were all havign a blast on it. Like 180 nose taps, all that. I get the bright idea to switch 180 over it. I do it once, and it felt good. I went in the next time with more speed, boosted like 5 feet straight up, cleared the tranny, and fell feet first, immediately my whole body slammed stomach first on the flat. I just broke my binding. Lucky.
Moral of the story is that 12 feet isnt all that high, especially when landing switch, and in softer snow.
