So just the color change on the shafts sounds like. I ordered mine with the Recoil 95 today is why I was curious. Thanks for the quick reply!!Which prototype shaft? The ones in my irons?
They are UST Mamiya Recoil Proto which is part of their line.
Our THP Experiences always come with equipment for every participant and in the last one we did with UST Mamiya, they made custom shafts to go in the iron set that everybody received.
