KING COBRA SZ FAIRWAY WOODS Not to brag or anything but theyre the Golf Digest 2005 Fairway Wood of the Year! The SZ is short for Sweet Zone..and thats the only thing short about them. A milled rhombus oval insert and thinner perimeter combine to create greater response across a gigantic club face. A new dual weighting system generates more efficient energy transfer for better ball flight. Rhombus Face Technology means a thicker center and thinner perimeter for tremendous response across the club face. This generates maximum ball speed. The dual weighting system helps create a deeper center of gravity to promote longer, higher ball flight. The hotter, larger face promotes higher trajectory and the contoured sole plate reduces drag. Standard and Offset.
