The VooDoo, introduced in 2007 was the first shaft from Aldila to feature S-Core Technology. It has a corkscrew rib on the inside of the shaft. It has a simple Flexural Signature, consistently softer down the shaft to 18” where it evenly gains stiffness toward the tip. The torque ranges from 4.5 in the 60R to 3.2 in the 70X shafts. The Aldila Voodoo profiles are consistent from weight to weight and flex to flex. The radial profiles are very good, the shaft can be installed in any orientation.
