Tsuk 1/1 is much more difficult than the Kasamatsu used by Ellie Black, Oksana and … almost everyone.
Mary Lou did half-on, full-off. (1.5 twists total)
Kasamatsu is quarter-on, three quarter-off (1.0 twists total)
Watch it on YouTube. (Right hand on the horse first, left twist on the salto.)
In addition, she trained Tsuk double full. Seriously.

Almost nobody does the more difficult version of Tsuk twisting. René Cournoyer from Canada is one.
