The HR model or non pro spec exceeds USGA C.O.R ratings and has a square to .5 closed face angle.
July 14, 200520 yr Author really???Thank you for this really fast answer. I thougt the 350 were only non conforming?? But no problem for me. I only play in Europe ;)
July 28, 200520 yr Even if you play in europe (as I do) I still think its worht using a conforming driver just so your mates can't accuse you of being a fraud when you outdrive them. lol
