I usually teach air rolls a little slower. It lets you sit a little deeper and build a bigger wedge between you and the boat.
Air tricks may not be the coolest, but I think every good rider should have a few in their bag. I've seen air mobe 5s, air crowmobes and air fronts over stacked canoes. Even an air front backside mobe (I've never seen that off the wake). Air tricks are a lot of fun to goof with and a way to break-up the wake to wake tricks. Air tricks done well have become a lost art.
