This is Maltby's 460cc flagship model, designed specifically to take full advantage of the USGA's new "Characteristic Time" measurement limit on spring effect. No one has ever accused Maltby of refusing to follow the trends, so this one incorporates all the latest innovations in clubhead design. (Also comes in a more conservative "professional" model.) Comes in a variety of lofts, up to 12 degrees. Said to have very solid feel through impact, unlike most titanium drivers.
