Side by Side Comparison of Simone Biles adn McKayla Maroney’s Amanar Vaults

Maroney’s vault is faster, higher, longer. Some have commented that McKayla is taller/bigger. Last I checked most everyone still thought being small was an advantage in gymnastics and there is no handicapping in the scoring system for size.

But this may well become a duel between the two over the next few years before Rio 2016. Bodes well for the US Team Score in 2016.
