The UST Mamiya ProForce has been with us for a very long time. It appears to have changed little over its time. I have told this story in an earlier review, but for those that miss it, I will repeat it.
During a lunch meeting of UST management after a tour win in the 90’s they reflected on how little attention the bland color of the shaft received in media. The engineer at the table picked up a jar of mustard and declared he would fix the problem, he would paint them mustard color. The tour rep was horrified with the idea. Over his objection, he was handed mustard colored shafts. Soon after, Jose Maria Olazabal won the 1999 Masters with the Proforce Gold golf shaft. As a result UST could not make them fast enough for the tour rep to hand out on tour. I have verified this story from three of the four that were at that lunch. It is a colorful (pun intended) story about the history of golf shaft marketing. It is now 26 years later and the ProForce shaft is still with us.
