I am looking at a new set of wedges, 52, 56 and 60 degree lofts. I am confused by all the new grinds and the various numbers assigned to them. I take very little and shallow divots, but sometimes chunk the ball on shots under 15 yards and am a 7 handicap. Do I get different grinds for each club? I have gone several times to be fitted at local retailers, but each suggests a different set up. Thanks.
