i just did my first today were i was really trying to land it. Just really went for it, couple of hints my coach gave me, when you go in, not a lot but carve the way you are going to spin, just a tiny bit so you are on your edge. And when you throw it, the motion is like punching your knee cap with your opposite hand, and commit. Atleast get your head around becuase anything is better then landing on your head.
only had time to do one, and dint quite land, but pretty damn close. They are easy, and super fun
