It is not the same as the Golf Pride grips, more akin to the LAB Golf putter grips.
I talked to Callaway and they told me that although you cannot buy it as a separate thing currently, they are looking into it because there have been many requests to buy the grip. I really think we will not be able to buy it anytime soon.
I don't know if I should wait or just buy the LAB grip 3° grip.
