Ping S55

Even in its second year, this club is as relevant as ever. Improvements from the S56 include a change in the lofts of some irons to achieve the proper distance gapping. The 6-iron was strengthened half a degree, the 7- and 8-irons are 1.25 degrees stronger, the 9-iron is 1.5 degrees stronger, and the pitching wedge is a degree strong. Also, a tuning port in the cavity helps lower the center of gravity, allowing the 4-iron to be weakened a quarter of a degree.
