On the Wilson Di9 irons the cavity and sweetspot have been placed between the centre and the toe based on the fact that 85% of shots hit by amateurs are struck from this area of the face. Compared to the Wilson Di7 irons, the sole is wider and the blade height is slightly lower, making long irons easier to hit. An insert is placed in the cavity and combined with increased mass in the heel helps remove unwanted vibrations. The wide tip of the shaft prevents the clubhead from twisting.
For a club that is created with accuracy as the main focus, the Wilson Di9 irons sit beautifully at address. The large heads instilled confidence without being too bulky to look down on. The off-centre cavity and sweetspot design is a new concept and, if the extreme levels of forgiveness are anything to go by, it’s a welcome addition. Where next?
