Handspring over the mat stack sideways, does not seem more progressive to me that the handspring to flat back. Learning to keep the body tight and straight in the flat back position will help the power of the vault develop in the long run, inwould say going sideways over the vault is going to end up with a lot of kids just arching over.
Here we have the girls do a handspring to flat back over the actual vault table, with mats stacked to the same height as the table.
Very interesting that they are going from a handspring vault for 4 levels (4, 5, 6 and 7) to going to timers after just one level on this vault. My guess is the new move up score of 34 in level 4 is related to this. Since they are not going to have kids spend so many years on this vault they want to make sure all gymnast master this foundation properly before moving on.
I am not a fan of replacing the handsprings tomtwo feet with handspring step outs. It does not seem as impressive and it is safer to teach skills with a two foot landing first before teaching step out skills. Two feet absorbing a landing builds in more margin for error when developing landings. A lot of super Flexi kids will just be doing fast walkovers rather than real handsprings.
Not a fan of the aerial being able to replace the front tuck in level 5, the front tuck is a staple in developing tumbling, especially in this day and age where there is so much front tumbling.
