i posted this is another place as well, don't remember where exactly but....
over rotating front flips is probably one of the worst crashes there is. going to far on a backflip sucks too but landing on your back is much more tolerable than chest first i think. high siding an edge is bad, urban stairs don't feel good, but over rotating has got to be the worst. i did a front flip on the set up jump at mammoth and over shot the piss out of it. landed in the transition literally goggles first. knocked out for like 15 minutes, and shouldn't have skied for like 3-4 weeks. i ended up taking it easy for 2 and then started skiing, but thats besides the point. the set up jump is pretty tiny, and i can not imagine what it would be like to anything similar to what i had done on a jump like the one in the picture.
take it easy man
