Olympic medallist Yang Hak Seon is reported to have upgraded his vault the “Yang” to a “Yang 2”. His new technique features an added half twist to his Tsukahara triple turn which earned him a gold medal at the London Olympics this summer. Of course, there is only a picture available to describe the vault but he is scheduled to compete at the La Roche Sur Yon World Cup in France next month, perhaps the vault may emerge?
More news outlets are beginning to report on the possiblity of an upgrade. Appprently Yang can land the vault 80% of the time and plans to show it at this October World Championships where he could then have it entered into the Code of Points. There is also a television news report available here.
