dude sms is like the smallest of them all, im in the crappy jibbers club so i go there, i went there last year and it ruled learned lots, there were people there that couldnt even do a 360
dude if you pop too much at the top of the wall you will land at the bottom of the pipe....not cool it hurts, you should pop the slightest bit so you will stay in the pipe and not land out side of it, practice makes perfect
sms is very good but smaller and friendlier, you probably wont hurt as much afterwards you also get a free take home video of yourself, where as if you want serious air go to high north but you dont get a video and you better be good
