Hey JT

Homer had a personal preference for Grip Rotation over Plane Line Rotation I believe too. Manipulated Hands Swinging or Hitting.

Can I ask for an opinion on the geometry of the straight shot presented above?

K, so and correct me if I have this wrong, assuming a short iron say, ball back of low point, club face square to the Arc of Approach (therefor pointing right of target, no divergence in path and face). To hit the straight shot at the target you then rotate the plane line to the left accordingly.

I can see this as producing a straight ball, no problem. But wouldn't this be a higher flying , shorter shot given the added loft of the opened club face? I see it as a great way to get over a tree say. Maybe I have things wrong. If I don't , why doesn't this show up in the data ?

Me I just Rotate the Clubface back to square per (dang is it 7-3) and expect a slight draw if anything. But there isn't much of one due to the steeper plane angles associated with short irons. Less divergence , less Out , more Down . I use that logic on the other side of low point sometimes for the driver , but take the draw (ish) and the true loft , compression every time with short irons. Now in bunkers I do that just sometimes......if I want to avoid a hop to the right you get with the open plane cut shot.

That and the HOgan thing trouble me. I dunno.

Thanks Pro.

Hey OB,
Now this is just me talking first of all. Im not tryng to debunk any theories by any means, just sharing what Ive seen and experienced.......but, while an open face would hit it higher if that were the only parameters, I would hope we don't have the ball so far back that a face is very open to the target at impact (unless we're trying to hit a high draw which would also be a less than stock shot.) Even with that though, angle of attack is going to determine trajectory way more than a face being 1 or 2 degrees open to a target. So, yes i would agree that most (not all) better players that get ball back, will end up swinging shallow and to the right eventually. The only thing I would say to the video is that you don't have to move the "whole" hoola hoop.
On your method, Im curious, have you taken video (DTL) of the a stock shot versus the one when you close face at address and compared? Every single time I have or taken video of a good player do this they actually change plane lines, particularly exits relative to target line.

Ive never goofed around with it on video or a Trackman personally ... which is why I was curious about whether the data reflected a floater type shot.

But ya I bet the plane line changes. Release maybe too. I see a lot of guys demonstrating ball flight laws , path vs face but showing a little hanky panky going on in their release. Ive got no problem with this, its just the tools of the trade. Its automatic.
