Hardest Backward Tumbling in Women's Gymnastics

Note that this montage focuses on backward tumbling. I know Raisman's first pass is awesome...but Arabians are forward elements. This also applies to Hong Su Jong's double arabian front half-out into Barani. That montage to come later. I also tried to find older gymnasts performing the skills, when possible. As a homage to the gymnastics of the 80's and early 90's. You didn't know Bogi had a double-double in her, did you? London Phillips is insane. I regrettably couldn't find footage of Hypolito's whip, 2.5 twist, front layout.
