A crooked spin is merly an extension of a usual spin.
A crooked spin is merly an extension of a usual spin. i.e.: if you can do a normal 540, you should try a crooked 540, wich means you spin 540 but with an angle of (more or less) 45 degrees in the air. Try this: When you're about to pull the (i.e.) 540 (clockwise) and you've prepared to make the "swing" move, try to swing from your left upper side to the right lower side (the move is kinda like bio, but your NOT flipping over)
