Tyson,

In regards to our grinds, they are not actually customizable.  Through years of research Bob and his team, have placed specific grinds on different loft/bounce configurations that have had the best success on tour. 

With the M grind, you will be able to find this on our new Vokey SM4 56*11. 

For a full list of grinds, their descriptions and what models you can find them on, please visit us at the following website
