I was about to abandoned my PXG 0211 driver with the senior version of the Aldila NVS Orange NXT shaft but decided to replace the shaft with a regular flex. What a difference it made in how the club feels and my confidence in it. Driving the ball the best in years. That plus superb service from TGCT. Liked it so much I ordered replacement shafts for my PXG 0211 three and five wood. Can't wait to give them a try.
