I have limited access to UST shafts as they do not provide review samples. This review is of the shafts available as a custom shaft selection from TaylorMade. The Proforce shaft has an interesting history. A lunch meeting of UST management after a tour win in the 90’s reflected on how little attention the bland color of the shaft received. 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 24 years later and the ProForce shaft is still with us. It has gone through updates to deal with driver head design and shape. It remains a viable design imitated by many shaft companies.

The KuroKage XD has a dual wrap of Titanium Nickel prepreg in the tip as you can see in this image. Titanium Mickel (TiNi) is an elastic wire that immediately springs back to its original shape when stretched. It is used to increase the tip stability of the shaft.
