The all new HSW-V a-Spec is non conforming material, according to the R&A rules. Especially the face comes into consideration in the a-spec model, because it is much more elastic than a regular driver face.
By utilizing a GF180 material, which is harder and stronger than standard face materials like stainless steel, the HSW-V is able to create a face 35% thinner. Matched with a compact looking 260cc head, it is able to create overwhelming initial ball speeds thanks to its Hi-COR, above the rules Ultra Extreme face.
With 14 degrees of loft, off the tee it is long and accurate and then it can be used for the second shot to attack the green. By incorporating a variable thickness crown design, the HSW-V FD is able to move excess weight towards the sole. This allows the center of gravity to shift deeper and further back. This is HSW or Heavy Sole Weight design which the club is named after. Creating the ideal center of gravity for optimal launch and maximum distance. Moreover the step sole design of the HSW-V reduces friction and resistance when the club comes in contact with the ground. This allows players to achieve maximum swing speed through the impact zone and creates more stable performance in various lies. The slit behind the sole improves body rigidity and increases energy transfer for maximum power.
