I was afraid that you wouldn't show Beth, as the video went on I was more and more worried :DD Especially when I saw the tweddle-ezhova-van leuween connection and it wasn't Beth
Aliya in a podium training video from 2011 bercy competition has done the combination at @1:31 but instead of doing a straddle stalder half turn after the pak salto she did a van leween. So she did a full stalder pirouette into the katchev into the pak into the van leween.
