So 15 years ago (if it were 2009 I could say 10 years ago and have a better argument) 720s and misty 5's were footage worthy. Its not like the human body has somehow become superhuman in 15 years to allow the tricks that are landed today, and most of us don't have formal lessons for this stuff.
I get that jump building has gotten alot better but other than that, not much has changed. My point here is, I suck, and I sometimes think, well 15 years ago the stuff i'm doing would have been in ski films, so really, is it just a small group of people who are physically capable of upvote worthy videos?
It isn't like JF and JP were purposely slowing down their spins back in the day, why is a cork 9 so common place today? Is it just more people in the sport means more gymnastically adept people are in parks? Or is it really the small technological improvements have really made that big a difference.
(I'm not talking about pros, obviously as the sport gained momentum and you could make money doing it, when you are in the park everyday all day you have time to figure stuff out.) But I have been trying this stuff for 5 years, and I am never going to ever do a cork 9, but I have to imagine, given the level of skiing just 15 short years ago, I am in the vast majority and the undiscovered gymnasts doing the cool stuff just happened to pick skis over a springboard.
