Replying to Cliffjumping: how high is dangerous?

so me and a few buddies are going on a mission the next week to basicly bang many women and cliffjump all over ny/ vt. we have a buncha spots picked out and some bigger ones (60-110 feet supposidly so i assume its like 50) and were filming for my buddies video contest so we all plan to throw some dubs. I can dub back and dub cork a 25 foot cliff solidly but never threw it on something bigger so its gonna be new to me doing it on something 2 or 3 times as big and i may over rotate some shit until i get the timing down perfectly. So basicly ns, how high of a drop onto the water can actually injure you worse than knocking your wind out or some bruises. Injuries like dislocations and broken bones or knocked out or worse. Whats everyones experience or knowlege of this? I know when i hit the water on a 50 its some solid impact....
