I would like to ask a Titleist Staff member if the comment of "all" Titleist forged conform to the condition of play status. It appears on your website that the 660's thru the 690's conform, but no mention of the 681's. I have also been on the USGA website and that indicates "ATR" for additional testing required, but would like a general sense from Titleist. Please advise. Thanks. "Patriot"
