Trick ID: 332
Whip position engaged just before the catch.
1 Back Somersault
Swing out and back to the platform. As you swing back forwards again, bring your legs up in front of you to quickly get into a Whip position at the frontend before opening for the catch. This trick seems like it should be similar to a Pelican, but because you can't sweep your legs up into the Whip position (the bar is in the way) it is usually less graceful.
