House of Forged "Prototype" LD
The HD PROTOTYPE shaft series feature MATRIX’S state-of-the-art “HD Design” technology, which incorporates a 16-sided hexdecogonal mandrill in order to increase elasticity in the butt-end of the shaft, while increasing the stability in the tip-section. This innovative engineering promotes a high-launch with the low-spin characteristics, which are necessary for monster drives. These shafts also offer some self-correction to decrease the side-to-side dispersion = the ultimate standard driver shafts. These shafts are offered in 45-gram, 55-gram, 65-gram, and 75-gram weight series to provide the maximum in custom-fitting for golfers of all abilities.
