I've built many clubs over the past few years. Most of what i do is re shafting for people i know as a hobby. Like i need more hobbies So i have laid hands on many a shaft. On a whim i picked up a A.X.E. Excalibur 6+ tour in "R" flex. There are a few times where i need a shaft profile that is between R and S. I have used Robins other shafts before. But this new shaft just blew me away. Not to mention some friends that tried it at the range. The fact that a $50 shaft can feel/perform as good as a $300 shaft. I'm going to put some more time on it. For now it's in the bag.
