Tony Hawk: Ride

I suggest doing this on free ride. On the half pipe you'll notice that there are floor boards with lines separating them. Lift the nose or tail at the last floor board to perform a stall (nose, tail, or blunt). Do not preform other tricks like "kickflip to stall" or something like that, this will not count. Keep doing stalls until your style meter goes past the line, this means it's ready to activate. To activate it, you must cover the front or back sensor of your board while on the middle (flat part) of the half pipe. if you mess up at all just press start on your controller and select restart session.

Message me on Xbox360 LIVE for help or more information.

This one is kind of a pain. I tried about 60+ times trying to get this. The stall is somewhere between a manual and an ollie. You just have to find that sweet spot. Plus, if you cover the sensor, you end up doing some lip trick. you have to do about 6-7 stalls in a row, with no other type of tricks in between. If you do something other than a stall while going for the achievement, just restart the level.

I finally got frustrated and just sat my butt near the big start button, and when I hit the flat of the ramp, I just shifted my weight slightly backward. Is that the cool way to do it? Probably not. Once you find that perfect spot, however, you should have no problems.
