If you go to the Vokey website, at the top there is  a banner that says Voke's Notebook.

Click on that then click on Vokey Tour Grinds. That should give you some good info

on all the grinds available.

                                               Cheers, Dave.

Since they are hand ground, just tell them exactly what you want and they can figure out what to do and which option it is exactly...if you are uncertain what you want consider getting a standard SM4 wedge and trying to determine what you would grind differently to make it fit your game best.  JAT
