What is the difference between spining and PUREing?
Spining is a nebulous terms that a lot of different people use to describe a lot of different processes. To some people spining means putting the shaft in a clamp and deflecting it back and forth. To others is means using a tube-like device to determine the straightness of a shaft. The SST PURE process, on the other hand, is an engineeringly sound procedure that performs a structural and performance analysis on every shaft to locate its most stable orientation. This is done by computer analysis, so any errors which might be made from human judgment are negated. SST PURE locates the Plane of Uniform Repeatability in every shaft, that is, the dominant plane in the shaft on which the shaft flexes. This guarantees a softer feel and more consistent performance from club to club. If any clubmaker tells you, “I can do the same thing as PUREing,” don’t listen to them unless you receive an official SST PURE printout. Your game is to important to be trusted to an individual’s judgment.
