I can't notice the different grinds, but the bounce is critical.

Dirin, sorry if this is late, but Mr. Vokey would probably suggest a lower bounce if you're a sweeper (shallow through the ball) and play on firmer turf conditions with firmer or packed sand in the bunkers. More bounce will help a digger (steep through the ball) or if you play on wetter courses with softer turf and/or fluffier sand in the bunkers. Good luck. Let us know how you make out.

54-10S is a good all around choice. 54-14F is more of a digger shot. 54-08M is a nice universal grind: you can play in soft turf and hard alike; all you do is play more of a digging shot back in the stance on hard lies. I play a 56-08M as a sand wedge and I play it everywhere.
