Layout full mount
Back layout full 1/1 mount
Kelly Garrison (USA)
While it’s tied with the Arabian mount for most difficult in the beam code, there’s little controversy over which is the actual most challenging beam mount that exists, and it’s this one. You know, because you have to maintain a straight shape with an entire full twist and all.
The best-ever example of the layout full mount probably belongs to Natsumi Sasada (first example), but even she has to pike that thing a little to find the landing, and when Kelly Garrison herself did it (second example), she typically would do the full twist in a fairly laid out position, especially in the early days, but then unabashedly tuck the actual salto to find that landing. Because you would.
