So I only got to do the run about 3 times before leaving for work.
I was having sort of a hard time getting used to the controls, especially the turning. I felt like I would turn WAAAYYYY too far in every direction when moving fast; it was like I barely had any control.
As far as tricks go, I don't know if this is the case for anyone else, but I barely know what buttons do what yet, but I'm pretty much doing tricks like I did as a kid playing SSX Tricky/3: Holding down both triggers, pushing the sticks in a direction, and pressing a face button. Just mashing and seeing what happens on screen. I'd like to learn them a little better though, since that isn't as fun as it was when I was a kid.
The button controls make most sense to me. Run yourself through the tutorial a few times and you'll start to get a feel for it. It does a good job of breaking it down, but here it is in text which may help you grasp it (pun intended) better.
Here are the four basic tricks:
X = left hand grabs left side of the board
B = right hand grabs right side of board
Y = both hands grab top of board
A = both hands grab bottom of board
And you can press two buttons in rapid succession (tap the first one, then quickly hold the second one) to do more complicated tricks. For these, the first button indicates what hand you use and the second indicates which part of the board that hand grabs.
Left hand tricks:
X->B = left hand grabs right side of board
X->Y = left hand grabs top of board
X->A = left hand grabs bottom of board
Right hand tricks:
B->X = right hand grabs left side of board
B->Y = right hand grabs top of board
B->A = right hand grabs bottom of board
Two hand tricks:
Y->X = both hands grab left side of board
Y->B = both hands grab right side of board
(I don't think there is a Y->A trick, but somebody please correct me if I'm wrong)
For ALL of these tricks, press RT and you will tweak the trick out.
To do your unique SUPER UBER, press any of the three trick buttons (X, B, or Y) and BOTH RT and LT.
If you're on PS3 it's the same, A = Cross, B = Circle, X = Square, Y = Triangle.
