I've had D and F in my 54 degree wedges and honestly preferred the F, even out of sand. I really want them to come out for a .14K for the sand wedges, but so far no luck.

The F grind bent strong by 2* is good for various conditions. Been playing 54-14F (52*) for a year now. Just switched to a jet black 56-14F (set to 54). My LWs are 60-06K and a PM Grind 64/10. I keep a 58-12D for courses like Torrey Pines and it is actually pretty versatile but the F and low K are better off tight lies.

I played K grind between 2019-2023. Its shortcoming is flop shots or open face (which is where D Grind wins out); however, it works better for hitting off hard lies vs D grind. Been a trade off.
