Like what the previous post sayz, you came up at an angle. Try instead of making a straight cut for the jump make a long, but quick carve right away to kinda give u a little extra speed into it. Also grab. Grab, grab, grab!!!! I'm trying to teach my friend that grabbing gives you air stability. Doing a 90 degree turn in the air isn't bad, you can always pull back. In fact 9 times outa 10 I turn 90, and pull a tweaked out stale, or melon, or even Truck Driver. I can't spin, I can do a front side 180 off a kicker, or a switch BS 180 on the ground. Thats my limit of spins, just so you can get my exp. I don't spin, so me doin a 90 and bringin it back is pretty sick. Like I said, GRAB!!!!! Even when your flappin (rollin down the windows) you can still get a grab and even back out. I've done it a number of times. Also, if you miss the grab, try again somewhere else quickly. Sometime's I'll miss method, and pull out indy. BIG Difference, but you kinda get what I'm talking about.
Sorry, I am a ramblin man. Also it looked like you were on your heal edge before you took off, u can tell u were leaned forward a little which is good, but the 2nd u were deffinatly leanin back, on your heal edge. So you started to spin before you even left the launch. If you spin on purpose it's easier to get back, If some thing makes you spin, u have no way to fight.
My 2 cents
