At the beginning of last year (2010) there was a rule change about grooves on the entire set of golf clubs. This rule made it so grooves could not be too deep and too effective out of the rough.
All in all, I thought it was a great move for the game of golf. For the most part, this rule didn't even effect the consumer, until now. Most amateurs can continue to use the old wedges with no problem. But if they want to try and qualify for a major tournament, like a USGA sanctioned event, they will need grooves that are conforming. A USGA sanctioned event would be the U.S. Open, of the U.S. amateur.
These tournaments now require that clubs with conforming grooves be used through out the entire qualifying process. Since these tournaments are what the amateurs usually compete in, this rule will effect them the most. So, if you plan to play at a section qualifier, get some new wedges to avoid disqualification.
