What was the night and day different it made? I own two of these and they play well but would use them more often if they played even better. Thanks. BThe "S" was used to designate an evolution in Ponzol's CAD machining that produced a better and more consistent facing curve. I have found on Ponzol M1's that the curves are rather short regardless of being the later "S" models or not. I just had Eric G. reface my M1 (s) and it was like night and day as far as blowing resistance by increasing the length of the lay.
Well, there ya go. I told you I could be mistaken!The "S" was used to designate an evolution in Ponzol's CAD machining that produced a better and more consistent facing curve.
