Just wondering if anyone had any experience (personal or technical) with the stock Exsar 60 Stiff shaft that is on the Mizuno MP-001. I remember hearing that Mizuno put a lot into this shaft and as far as stock shafts go its up there...but again I'm not too sure I was hearing the truth or if the guy was just trying to sell me the club. I was thinking or replacing it with the Fujikura Tour Release 27.3 Stiff. Any experience with either shaft would help. Thanks.
