What Honma Says:
UT for High Trajectory and Take Close Aim at the Pin - Sole thickness and CG flow design for each club. Achieve stable direction performance and straight line. Optiomal CG design for each club for aiming for the green in any situation.

Details & Benefits:

• Tungsten weight - Enhanced draw bias by placing 14g weight (inclueded screw) closer to the back heel.
• Uneven Thickness Face & Crown - Improved repulsion performance by thinning the face and crown. Furthermore, the repulsion area has been expanded. (Compared to previous
  model)
• Designed Specifically for Each Club - Sole thickness and CG flow design for each club to achieve ideal trajectory.
• Adopt the industry's first high-strength carbon sheet - The ARMRQ shaft has evolved to allow for easier contact and higher trajectory. This time, we purposely reduced
  the number of axises, which have increased with each model change, to reduce weight*, while maintaining strength by adopting a highly elastic 70t pitch for the fibers.
  This makes it possible to reduce weight, make the flex more, set the kick point closer to the hand, and place the balance point closer to the head, achieving high
  reproducibility "straight-line". *17% lighter than the previous model for the fabric.
