  Designed for the mid to low handicap golfer who enjoys extra forgiveness in their iron set Taylormade officially announced the new R9 Iron set in Japan and on it's website today. The set itself which is almost made of 2 different designs gives the golfer a long iron advantage with a hollow undercut and a high rebound face while the 6 thru gap wedge become more compact and solid without as much of the undercut forgiveness.

Created with the help of 6 time major winner NIck Faldo. A classic looking set of irons which while retaining the feel of a players club are more forgiving than they look, especially the long irons. The weight has been redistributed to create a much lower centre of gravity and this combined with a high moment of intertia allows for a much higher launch with the long irons and more spin control with the shorter ones. Fitted with KBS tour shafts they are a great set for the mid to low handicapper.
