Typhoon So how are they measuring?
I'll look it up, but I seem to recall it is soling the head at 60*.
**5.0 Procedure for Measurement of Club Length
5.0.1The measurement of length is made with the club set on a horizontal plane while the sole is set
against a 60 degree plane, Figure 5.0.1. The length is defined as the distance from the point of
the intersection between the two planes to the end of the grip.
Figure 5.0.1– Convention for Club Length Measurement
5.1 Place the club length measuring apparatus, Figures 5.1(a), (b) and (c), on a flat, stable surface**
So, they lay it flat, instead of standing upright.
