I'm a club maker. Fujikura is a premier golf shaft manufacturer. I just removed two of your Callaway Green shafts from a 2017 Epic driver adapter and a 2017 3 wood adapter. Both of the shaft tips unraveled at the end. I've been making clubs for 30 years and have never seen such poor quality. Was 2017 just a bad year or have I missed something? And no, I didn't overheat the shafts. Thanks for any comments you may offer.
