Ping Zing 2. Offering the key weighting features of the Zing iron with more rounded shape, the Ping Zing 2 continued the emphasis on "extreme" weighting to optimise forgiveness for greater accuracy. The Ping Zing 2's sole design not only complements the extreme weighting design, but also reduces the surface area in contact with the turf to promote clean ball contact. Lee Westwood used a set of Zing 2s in helping to thump the Americans in the 2004 Ryder Cup.
