I bought a 913 D2 from Golfsmith that was used but the only problem was that it is a regular shaft and I need a stiff. I was looking around online and found replacement shafts cheaper but I wanted to know if it was easy enough to change out the shaft on my own or was it difficult because of the SureFit Tip. Basically, is it possible to take the tip off the shaft the driver came with and put it on a new shaft? Thank You.
