Titleist, Vokey, Scotty...which I haven't updated my signature with yet.
As a fun side game, my Scotty is "the one he never loved". He absolutely can't stand that his name is on these putters. They are one of the only ones not on his website. Any guesses on which Scotty model I am talking about?
Also: feeling like I'm keeping a straight left AND right arm. The result of the first feel I just mentioned is that my left arm is actually able to rotate around in a more fluid way because it is no longer slightly pressing into my pectoral while performing the turn (actually making a bigger deal than I would've thought). On top of that, the feel of keeping a straight right arm is really helping me change the picture and get into a more professional look with that arm at the top of the backswing.
