Ok. I trimmed 1" off the tip the M-flex shaft I had and plugged it into the Jetspeed head. Whatever I did was absolutely perfect for the guy I built it for. Played with the guy today and he hit 5-10 balls on the range with it before our round. All pretty decent drives.
On the course the guy qas crushing it straight and long. Told me he has never hit a driver so well in his life. Was getting it out there where I hit it which is not short. 260-280 yards. Told him the price was $30 but he gave me $50 and wouldn't budge when I tried to give him $20 back.
