Just recently got fitted for a Vokey SM6 K Grind 58/12.  I must admit - when I played my first few rounds I did not hit it very well.  I was curious - the K grind is well known for being forgiving out of the sand, which is what most people use it for.  I usually have one club around the green.  
Is anyone else playing a K grind around the green, and not just in the trap?  
Update: now that I'm used to it - wow, it's crazy good!
