That's awesome. My best friend from Jr. High and I used to go nuts on Razor Scooters! I've always enjoyed skating and snowboarding more, but we had a blast on those scooters. They're so much easier to blast off of huge ramps with. I think the best trick i ever got to was 360 double-whip off of a pretty respectable pyramid at a local skatepark. You threw me back about 10 years with that video!
I'm too big for scooters now but I'm sure I could bust a tailwhip still. I'm kinda big for my skateboard too. Every time I go off of anything with any kind of size I can just feel that plywood stressing. Luckily I can still go off with my wide snowboard. (I'm 6' 205lbs if you're wondering)
