I was fortunate enough to talk to someone from Cleveland Golf at the 2010 PGA Show regarding their new CG 15 Wedges. He talked about the grooves specifically and how they conform to the new groove rules. The lighting was a little too bright for the face to come out clearly on video, but below you will find a picture of the face showing the detail of the Laser Milled Grooves.
Here is the footage I took. Sounds like these Laser Milled Grooves could help with spin once the new groove rules take effect!
