keep the handle in. If done correctly you rotate around the handle, and you can use the handle to speed up, slow down, or stop your rotation.
On your 3, the spin is half the battle. If you can ride away from it with no handle then you're half-way there. Cut as soft as you can and still clear the wake, pump the wake and take the trick straight up, give the handle a slight tug with both hands and pass it. The edge is the key.
For a while I thought I was edging soft enough, and then I rode with someone who told me I still needed to edge softer.
