I have a Callaway Paradym driver with a Hzrdus shaft in it. Began using it last summer. About 30 rounds into using it I would notice that, after hitting a drive, while using the club to brace my reach for my tee, I would hear a cracking sound coming from the grip area. I have recently been hitting a lot of balls in my simulator room and the cracking sound seems to be worsening. Any thoughts. BTW, my swing speed is 90-92 mph
