While watching the ski big air last night, I was reminded that bio spins existed. I thought about how they were just front corks. Then a thought hit me. If cork has an inverted cousin called and spin, does bio have one? I have never seen this before and have no idea what it would look like. Does anyone have any videos of these? And what are they called?
