I always thought the kip-up was a cool move... but never learned it. Now at my age, it's not even on my "to do list"! I wish you good luck, and keep us posted.
Now, on a slightly different topic... you said you were interested in learning this for your self-defense class? I'm surprised, since I never thought of a kip up as useful self-defense move. It's a great stunt, to be sure, and looks great in exhibitions and movie fight scenes, but I can think of several better ways to get up from the ground in a self defense situation. In fact, aside from the possible "element of surprise", a kip-up leaves you really exposed and vulnerable in most self-defense or fighting scenarios that I can imagine.
