Used Ping Scottsdale TR Single Irons

TR is True Roll: grooves milled deepest at the centre of a 6061 aluminium insert and shallower toward heel and toe, so a strike off the toe leaves the face at close to the same speed as one from the middle. Twelve heads at launch in spring 2013, sorted by stroke type, with an optional adjustable-length shaft. Anser T, Craz-E and Senita B followed that October.
