The Aldila XTORSION Copper features a stiff tipped, Counter Balanced design along with a new and unique woven graphite material on the outer layer of the shaft at the tip-section. This Multi-Axial Material Bias Angle (MAMBA) Technology places a high-tech material on the shaft in a +/- 45 degree fiber orientation. This unique use of a flat weave material on the exterior of the shaft provides significantly improved torsional stability to this counter weighted shaft in the lower half (tip-section) where the greatest percentage of twisting occurs during the swing and at impact. Features: Stiff tipped, Counter Balanced design delivers distance and control. Manufactured using MAMBA (Multi-Axial Material Bias Angle) Technology, which places a high-tech material on the shaft in a +/- 45 degree fiber orientation, providing significantly improved torsional stability in the lower half of the shaft. Designed to produce a mid-launch with low spin.
