Swing out and turn around. At the platform, lift your legs up into a Heels Off position with the head back to look for the catcher. As you reach the front end, let go of the bar and catch the stick. Your heels remain on the bar for a split second. This trick is most often performed on a bar to bar rig, but can be caught with a catcher and stick.
