HS/FS Off-Axis 360
1. There are actually two ways you can do this move. One is by going all the way to 540 and then shifting back, and the other is just committing to a 360 off the wake. I would opt for the latter first. Then work your way to the early 360. Getting your body not to spin to 5 takes a lot of arm strength.
2. The key to stopping your body in the right position is all in the head. As you spin, stop your head by looking away from the boat. This spin feels more like a 180 than a 360.
