It's 25 inches long so it meets club length requirements, would it meet traditional and customary rules.
Also anybody have experience with a short club?
No it isn't.
Grip down on an existing club. A short club is a waste. I cut down my first club, a bargain bin 7-iron, when the grip wore out and the shaft developed a rust spot. It was pointless.
Kudos for even being able to get in that "Wie" position.
The first time I saw her putt that way I tried to demonstrate it to my wife and I found that I couldn't bend over and keep my back that flat. No danger of me ever trying that style.
