Jim, consider studying the "grind" page selection guide on the Vokey website.  It may offer some insights into which new SM5 grind to purchase that will compliment your game best.

Jim,

You should also try to find a fitting day or a local club that has some wedges for you to hit.  The 56* is one of the most important clubs in my bag.  You don't want to make that choice lightly!
