there are still tons of tricks to do other than the normal slides, and crazy spins, sure i guess rollerblade grinds are one of them you can do on gayper day, but there are still so many different variations of presses, crooks, and other stuff. i was at the us open at copper last year and i was watching all the pros riding through the park just dicking around on their free time, and there was some crazy shit happening, like i think it might have been andreas, poping a 180 doing a huge nosepress so he was switch then 180 out, and it was a long box too, and all the butters on to press and spin combonations i saw were pretty crazy too. and its alot more original and creative than just grabbing your ski on the rail, i thought that fad was gone like 3 years ago.
i dont really have a problem with people doing rollerblade tricks, personally i think they look completely horrible, but if people want to do them thats fine i guess. im just saying, its not gonna progress in that direction, mostly because it isnt a skiing trick. they are pretty much taken straight from rollerblading, while there are plenty of skiing original grinds that are still progressing and popping up, that look much better.
