To tell you the truth, you should work on at least an indy grab. Practice off small hips. Suck your knees up and let the board come to your hand. Once you get used to this and then move it to a kicker, you'll notice you are a lot more stable when you do a simple grab. It prevents your arm from rolling the windows.
I don't think I can grab indy on flat ground. I'm incredible inflexible right now. I need to work on that.
