I recently purchased a new 915D2 with the Rogue 70 S, unfortunately I purchased at a shop whose fitting area was under construction so was only able to go based off of hitting my friends D2 with same shaft, but in X. I know the X felt a bit too stiff for my liking, but now that I have this in Stiff, it feels way whippier than a regular. The club hits too high with too much spin, and feels all over the place. What can be done to correct this?
