It depends on what your preference in shafts is. If you like the feel of the DGs then I would go with the KBS, they are a little more like the feel of a DG with the flight of a Rifle.
If you like project Xs or Rifles then I would go with the Spinners, I had some in my old wedges and I felt that they changed the swingweight pretty severely( lighter shaft took the swingweight up the static weight down), so I would look into getting that where you want it.
