Yonex Cyberstar M II. The Yonex Cyberstar MII Fairway wood features a CH-1 maraging steel head and incorporates the successful Muscle Power face technology to maximize both explosive power and forgiveness. A tungsten insert helps square the face at impact and lower the centre of gravity for higher trajectory. The sole shape and shallow face design further assist in getting the ball airborne more quickly from a variety of lies. The Cyberstar MII Fairway woods feature a carbon graphite shaft that incorporates brand new high-stability technology for improved accuracy and the Centrifugal Force System (CFS) for greater distance with a higher trajectory ball flight.
