Closest Grind on SM8 to old V grind

To match the width of the V Grind, the L Grind is the closest. But keep in mind, the L Grind has 5° less measured bounce, so it will play as a lower bounce wedge.

To match the measured bounce (almost) - go with the D Grind. It has a touch less measured bounce than the V, but more width, so it will play in a similar bounce range, but wider.

If you just have to have the V Grind - choose your preferred loft in SM8 Raw, add a handground option and in the comments, specifically ask to make it a V.

Voke's team can handle the rest.
