Matrix Radix Tour 6321 Graphite Wood Shaft
The base for RADIX is The HD design, giving RADIX the most advanced internal structure in its class. Along with the internal structure, an experimental variable tip-to-butt ratio design is introduced with Radix. The ratio specs change by flex: ball flight lowers as flex stiffens, adjusting for the progressive needs of progressively harder swingers.
The HD Design refers to the hexadecagonal (16-sided) internal platform on which the designs are built. HD allows for new levels of structural strength. With the stronger 16-cut butt section, Matrix engineers are able to better structure and strengthen the tip section without adding overall weight, and, at times, even lowering balance points to better match high MOI, low CG heads. The result is a stronger tip-strength-to-weight ratio than with any previous Matrix shaft.
The internal HD structure can be made more consistently uniform than a circular design, further reducing the need for specific orientation during installation. In terms of performance, shafts with the HD label will produce flatter, more piercing Tour-type ball flights and a more stable, crisp feeling.
