Tassilo points out that the 2000 Olympic Vault Champion did NOT compete Kasamatsu as do 99%+ of male gymnasts.
Instead, he did Tsuk.
Right hand on first, left twist.
Watch Deferr on YouTube. (1min 45sec)
Tsuk is significantly more difficult.
Leave a comment if you know anyone else competing double twist or higher with Tsuk, not Kas.
