@SHistorians I would tend to agree the wear pattern would seem to render bulge and roll irrelevant in irons. My only thought is he is taking the physics of the properties to the extreme.
@SHistorians@USGA Amazing round. I took some kids lessons then, but wasn’t into the game. Around 1978 I started getting into the game and people still talked about it. It eventually prompted me to purchase “Pure Golf “ by Johnny Miller. Still one of my favorite instructional books.
@SHistorians@PGATOUR I remember it being called “protecting par”. At times I can lose interest in the weekly events that turn into a putting contest. I want, just once a year, to see par really mean something. I’m ready to lock in this week and see the best overall game rewarded.
