Sorry P but you are way off base here :)
12 is a pretty big advantage on either pin.
15 is a huge advantage on either pin.
16 is a huge advantage on the back right pin.
17 is a huge advantage on either pin.
Sure you're gonna have rounds where the pins/yardages line up for you and the raptures are fine. But the g10 will just be able to give you birdie opportunities from many more yardages and from many different winds.
