Working with Jason gave me the insight and assurance I needed to get through a testing and retesting of the driver shafts and club heads available today. After the work, we located the shaft that works for my swing, but none of the current driver head designs fit me better than my original M1 head. Awe agreed that we would wait for the new driver heads to come out in a few weeks before making a decision. Great experience so far, and looking forward to the finished product.
