Aldila launched the Voodoo shaft, with S-core technology, in summer 2008. The S-core - or ‘stabilised core' - is what Aldila says sets the shaft apart, and consists of a high-modulus carbon stabilisation rib running the length of the shaft. The theory is that the shaft's cross-section is significantly stabilised, so that the shaft's ‘hoop strength' is some 80% stronger than conventional graphite. Aldila says the result for the golfer is less shaft ‘ovaling' during the swing, which gives the shaft a better energy transfer into the back of the golf ball. That means faster ball speed and greater distance.
