Doesn't work, got a kind of happy accident though, it does make your guy crouch down which makes some tricks look better. I've uncovered a few techniques to make tricks look better too:
When doing 360s, 180 flips etc, use the boning/tweaking with the right analogue to make it look more 'real', like for instance in a bs 360, you can push up on the right analogue as you come in to the middle 180 to give it the tail drag which usually happens, then pull back on the stick to give it a pivoty look. Looks amazing when done properly on the flat.
Also, although the tricks look the same switch and regular, if you do a quick 180 or come out of a rail to fakie, yo can trick the computer in to thinking you're still going forwards, then do the motion for a nollie heelflip and out comes an amazing looking switch heel. [/nerd]
