The G10001 non taper grip is a specialty grip and will feel larger in the lower hand. The core diamter does not dictate what the outside diameter will be when installed. The .580 is actually a larger outside diameter than the .600. The final size depends on the how the shaft butt diameter matches up with the grip core size. if you use the .580 version of this grip, which is already oversize, on a .580 butt diameter, it will still be oversize. If you put the .580 grip on a .600 butt diameter, it will actually be 1/64 larger. If you use the .600 on a .600 butt diameter shaft, it will be standard size for this grip. Again, this grip is non tapered and even at "standard" it will feel larger. If you truly need a smaller grip, you may want to look at tapered grip offered in "undersize" options. The Golf Pride CP2 PRO (GP0107) and CP2 Wrap (GP0110) have undersized options as does the Lamkin REL Ace Black grip (LK0112).
