I can't spin to save my life, but for some reason, love a good indy shifty and boot them way into the flats. For me, I take more of a seated approach, and once I leave the wake I go for the grab, then just let my body drift backwards. Put the handle behind your back like you're going to pass it, but just hold the grab. It's kinda strange at first, and as Ryan said, you're not going to get turned all the way around the first time, but just let it drift back. Eventyally you will get to the point where you can look at the wake/lake behind you. When you're nearing the water, it's pretty easy to spin back to normal for the landing.
Start slow letting them drift back, then as that gets comfortable, go a little further and a little further. If you can turn your head and look in the opposite direction of the boat, it helps the rotation, but make sure you are comfortable with the drift before doing this (but it does make them look sick!)
