Sorry, but I call fowl. It shows how you still have a lot to learn. A bwo is a HECK of a lot easier to learn than a cartwheel on beam, because you can see where you are going. A cartwheel is a blind move. I have heard my daughters' coaches say this. I have also read it many times on here.I'm pretty sure a robhsbt is more difficult than a robhsbhs, a fly away layout is much more difficult than a 1/2 twist dismount, and a bwo is more difficult than a cartwheel on beam.
And for many children, the robhsbt is so much easier...my child being one of them.
