The heart of the Aldila VooDoo shaft is the new S-core technology -- a patent-pending stabilized core technology. The S-core boasts a high modulus carbon stabilization rib running the length of the shaft. The technology's sole purpose is to increase distance and accuracy through stabilizing the shaft's cross section. The technology has been reported to increase the shaft's hoop strength by as much as 80% over conventional graphite shafts and as much as 60% over competitors
