These came out when the new groove rule went into effect to be able to identify the wedges that conform to New 2010 U.S.G.A./R&A Groove Rules. They were announced in late October of 2009.

After the first Spin Milled wedges were made, the next series was the Spin Milled CC. The CC's were the first wedges that conformed to the USGA requirement to replace U shaped groves. The only difference on the back of the wedge is the spin mill logo background is gold on the CC and red on the non-conforming prior generation wedges are red. If that wedge is only identified as Spin Milled, my guess it is a CC model.

Thank you guys, this has been driving me nuts!
