Most of his issues are coming from the gate IMO. Doing the somewhat hybrid one handed gate like it currently is, is really impacting on line control at the turn in. This is causing a delay in getting on the gas and not being in an ideal body position into the first wake. Either go later on the pull out and have less of a glide, or stay on the handle with 2 hands for longer with a slower release. In other words, go watch video after video of Terry Winter.
The goal of being able to maintain better line control through the turn in, is to hopefully be a little better (dare I say it) stacked behind the boat, and not rely on muscling things as much with his upper body. Seems to be a lot of arm pulling going on, which is reducing outbound swing, width and speed also.
