Well, judging from the illustration on that website, I don't quite understand why SFOG is calling it a Stand-Up Gyro-Drop. You are not standing, you are dangling while not in a sitting position. Personally, I believe the should have called it Vasectophobia instead of Acrophobia. It seems it will not only be painful to the male species, but it also will sterilize several. I hope for the male's sake that the drawing is inaccurate...
