Funny thing happened after buying some graphite shafts for Irons, Matrix Studio 84’s. One set of shafts sold as Regular, the butt label is showing “R” at CPM 279, while the other set sold as Stiff with the label showing “S” with a CPM 279. Does not the CPM dictate the “stiffness” of the shaft? So what gives…?
Thank you!!! One would think the labels would be generated at the time of testing and if anything the CPM number would be the least likely item to screw up…or is that wishful thinking?
Your best guess on the CPM being correct vs the “R/S” labeling being incorrect??
