Has anyone with Carbon Fiber Shafts ever drilled into it to attach a Sun Ray Meter or a Probe.?...I am worried with the Carbon Fiber being like Fiberglass it might crack or frey when installing Pop Rivets or after lots of use...I have been thinking of keeping part of my Original Metal Upper Shaft and just using my Lower Two Piece Carbon Shafts but would prefer all Carbon Fiber....Please let me know....Thanks.! ....John
