Except where are you going to find a 25' long putter than conforms to the rules of golf? I can't imagine that a putter that is 25' long exists and has been approved by the usga. And I don't think you would be able to justify calling it a club, if its only purpose is to measure drops. Note this portion of the Appendix II, specifically the parts I highlighted in red.
At the very least, to get around that, this unscrupulous person would have to actually putt with the 25' putter.
This as well.
I have always used the 2 3/4 Pride tees. I tend to keep the ball teed up lower and have done the impact tape to prove I don't need it teed up any higher. I am sure I could change my swing to match a larger tee but I do not have an issue with launch angle or distance
I dont think you need to even buy a set of bigger tees but instead go to a course (or location) that has short grass and just tee it up higher. It might take some balancing but you should get the gist of it
My current iron set has shaft tip plugs for swing weight and these do not look like it. And my weights were in the shaft tip not the bottom of the hosel. My swingweight scale measured out the set between D1 and D2.. Pretty close to stock. I called Cobra and they said it is most likely a shim that was created because of boring that probably took place to mess around with the head weight and they didn't want the shaft to get too far in the hosel. Sure enough, When I took off the 8i head to compare (the head that still has the red hosel plug intact) the 8i shaft had a metal swingweight plug in the shaft. The 7i shaft didn't. In all, I can tell a tinkerer had these clubs before me and polished them up before selling them off to 2nd swing.
