Despite the new USGA groove rules now in effect for all Tour play you would never know anything has changed for most of the pros' short game. The new conforming wedge grooves actually produce a higher trajectory with medium ball spin (for soft landings) and result in almost no appreciable difference in distance for most touring pros.
The pros hit the ball longer and higher than almost all amateurs and can produce more ball spin even with the conforming grooves. However, the new grooves don't help the average golfer at all, yet will be required on all irons as of 2024.
The difference between touring pros and the rest of us has grown from a gap to a gulf, and the USGA's equipment rules exacerbate that distance. As many golf industry observers have noted, if golf is to grow in popularity equipment design and regulations need to benefit amateurs, not punish them.
As reported in the recent golf trade publications Ping agreed to a ban of its original Eye2 clubs on the PGA Tour. The rather tiresome hissy fits that some of the Tour players had over Phil Michelson's use of Eye2 wedges this year prompted John Solheim of Ping and the PGA to agree that as of March 29, no Eye2 clubs made between 1984 and 1990 will be used on the major professional tours.
Solheim expected this to happen when the USGA first proposed new groove rules in late 2007. Grandfathering in the Eye2 clubs opened up a can of worms that no one needed or wanted outside the USGA.
This new prohibition does not apply to amateurs where Eye2 irons and wedges can be used indefinitely. The new groove rules don't apply to amateur championships until 2014 and won't apply to club events until 2024.
