Britt,

Comments in another forum said GW tested the M890 shaft vs the autoflex. The two shafts profiled identical.

Is there something going on with the M890 shaft we might be overlooking? I have an older PING I25 Driver that I like to stick different shafts in as my tester club to see if I can beat the performance of the custom fit PING 425. Sometimes the cheaper shafts surprise me. Now I am intrigued to try the M890.

Can you shed some light on the design of the M890 and what you find in your testing please?
