Sean, although I haven't receive the email that would contain my specs on wedges from a fitting a week ago, Thursday, I think your question can be answered by the different grinds and different weighting found in SM6 technology/engineering. I believe it is because of those grinds and weight distribution that the SM6 will be more fit and effective for the player and therefore allow a player to perform better shots they intend to play.

Try them out or get fit. I demo'd the SM6's at my course for a range session and a round, and then placed an order for a 52F, 56S and 60S. They feel incredible, the progressive weight really works (great gaping to my 47* PW from the Vokey GW, and lower flight on the LW full swings), and they obviously have great spin.

I hit my pitches/chips almost exclusively square-faced, so I found the F and the S to be perfect. I struggled with the M, but if you like to open the face and hit high flop shots, then M should work for you. YMMV.

I ordered the Jet Black finish.

Good luck!

What they said above. I personally replace my wedges every 2-3 years due to wear. I'll get them regrooved once or twice but after that I'll replace them. Depending when you got your wedges being that model was initially produced 2-4 years ago. You may just want to jump in and get new ones. If you only got them a year or so ago I would go get fitted for wedges and see for yourself...you'll probably want to pull the trigger and get some!

Well said Darren.
