The whole length of the club is 46-48 inches. A swing balance by a 14-inch balance measurement method is C5-D0. The inertia moment of the club is 2,850-3,000 (kg cm<SB>2</SB>) at the rear end of the grip. A forward flexibility is 140-170 mm and a backward flexibility is 100-130 mm. A difference between the forward and backward flexibilities is≥15 mm. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
