USGA 2010 Conforming Irons and Wedges Database - http://www.usga.org/InfoClubsDB/index.asp
It looks like my MX-23 conform and so do the MP-30 irons my son plays. My other son has KZG CB and they do not conform. Not that anyone of us is playing professional matches. Just nice to know if a set conforms or not. Now our Vokey wedges do not meet the 2010 groove rule, although the heads are about 5 years old (pre SM). _____
