The Wilson Staff Di9 iron is the latest design from the company who have produced more irons than any other company in the world, capturing 61 major championships in the process. The Staff Di9 iron is a technology-driven design that delivers a combination of power and a softer feel while maintaining longer distance. The Di9 boasts an increased hosel length that gives the club a higher MOI and stabilises the head. The club’s sweet spot is expanded by the by the toe-friendly cavity which also shifts the centre of gravity towards the outside of the head for increased forgiveness. The Staff Di9 is further improved by inclusion of a soft urethane shock-trap in the heel that together with the Wide-Tip Technology shafts helps to minimise twisting on off-centre hits. The shaft is also the lightest ever wide-tip and at 99 grams ensures a higher club speed for greater distance. The Staff Di9 also utilises an innovative distance gapping system that has a 3.5 degree loft strategy to ensure smooth gapping among the shorter irons (most clubs on the market have only a 2 degree gap between the longer irons with up to 6 degree variation in the short irons).
