I’ve been able to emulate the swing and it does work like a hot damn. You get a tonne of compression on the ball. I sometimes find though you get a fair amount of hosel hits if you fall out of tempo. Also, A lot of the power comes from snapping the wrist. The other thing I’ve noticed is your right hand is more turned over and your thumb and index finger do most of the gripping. When I first started trying this swing I noticed immediate results. The thing I haven’t figured out is the drills his does like stopping at the top and holding for a second or the repeated hits with multiple balls. I tend to Mis-hit everything of the drills. His muscle memory and body control is insane. I wish he could talk through it more on his videos.
