Yonex EX DEMO Cyberstar VM-1 Irons (Graphite, 4-SW) The Yonex Cyberstar VM-1 irons feature an over-size SUS 431 Semi-soft Steel head and face, with a V-CON Core (graphite/elasotmer composite) for extra feel and increased repulsion.Yonex engineers have been able to create a thin face (3mm) design that is reinforced by the V-CON Core allowing the size of the sole and head to be increased, producing a lower and deeper centre of gravity for a hi-launch trajectory. This is ideal for any level of golfer who wishes to obtain a high ball flight for shot stopping control even from the long irons such as the 3-4 iron which can often be not only difficult to hit but also control. The V-CON Core supports the face but it also absorbs any unwanted vibrations for a crisp responsive feel of the face allowing you to get a true feel on those quality strikes and real sense of purity from the blade. The Yonex engineered Carbon Graphite shaft incorporates a brand new Hi-Stability technology for improved accuracy and when combined with a Centrifugal Force System (CFS) the distance results phenomenal.An excellent build with superb reliability the Cyber star VM-1 Irons are built to improve the mid level golfers game, developing it into that of the elite golfer. An excellent price for such a highly established set of irons, don’t delay and buy today.
