I used to skate a lot from 2003 to around 2011 mainly because of tony hawk pro skater games, but I stopped due to some really bad bails and injuries that made me scared for my life
But I used to land some RAD tricks, the hardest I could land was kicklfip and some random freestyle stuff (great fan of Rodney Mullen)
Now I just "skate" on skater XL on steam, for me is the best skate sim out there.
