The current line of F2 Golf Plus Series Wedges have the “U” shaped grooves. However, the F2 Line of golf clubs continue to be legal to play in non- expert professional competitions. For a more specific understanding of the USGA's rule concerning groove technology, please read below.

USGA Rule for New Grooves on Clubs

1. These new groove rules become effective for all new clubs covered by this rule change that are manufactured on or after January 1, 2010.

2. A Condition of Competition requiring the use of clubs that conform to the new groove rules for competitions conducted after January 1, 2010 will be added to the USGA Rules of Golf.  The USGA recommends that this Condition initially apply only to competitions involving expert professional players at the highest level of competition.

3. The U.S. Open, U.S. Women’s Open, and the U.S. Senior Open will adopt the new groove regulations for championships conducted after January 1, 2010, per the expert Condition of Competition. This includes all qualifying events for these championships.

4. All other USGA championships will apply the Condition of Competition requiring the new groove regulations for competitions beginning January 1, 2014.

5. Currently conforming clubs manufactured prior to January 1, 2010 may continue to be used in all situations wherein the Condition of Competition is not in effect until at least 2024. The final decision regarding the ongoing status of these clubs will be reviewed no sooner than 2020. If it is determined at that time (or later) that the rule change should apply to all clubs, there would be a minimum 4-year implementation period.
