Mizuno introduces it's all new JPX line for 2009. The new JPX E600 Forged iron is an advanced one piece forging made from soft S25C steel. It features a 30g tungsten insert in the 4-7 irons to help get the ball in the air and lower the CG for optimal trajectory. The E600 Forged uses a deep cavity design which creates more forgiveness on off center hits and a pure feel at impact reducing the vibrations on misses. Strong lofts and a mid sized package equal super performance coupled with forgiveness and feel. Available standard as 4-9PFS with mid 90g NS Pro 950HT in R, SR (Stiff/Regular) and S flex. Also available with JPX Quad HT graphite in R (52g) and SR (62g) as an upgrade.
