Kuchar's swing is flatter than orthodox at the top (below the turned Shoulder Plane).
So, this makes him LESS able to use the force from his right shoulder to power the arms and clubhead.
So what?
He make a very standard pivot--tilt wise, but does so with the LOCATION of his torso at the top pretty far to the left.
So, this makes his less able to do a good "RUN UP" before his "JUMP," which makes his pivot rotation less able to generate maximum speed.
So what?
A really tall guy swinging on a flatter plane has the club in basically the same location to the ball at the top of the swing, as a shorter guy on a more orthodox plane.
So what?
If you can generate enough speed, and get the club drawing a good line, and you can control the D-Plane, and to do it you need to swing like Kuchar, go right ahead.
I gave two lessons this year to folks who are "Stack & Tilters" and I fixed 'em up really good using that pattern.
So what?
I wonder if they'd fix a "Never Hook Againer" who needed help, with the NHA2 pattern?
Don't put the Stallion in a box, folks.
