What Honma Says:
Achieve longest distance performance organically - By placing the weight closer to the back heel, the ball-catching performance has been improved. Shallow and bigger head area structure maximize the height of trajectory and carry distance at tee by FW.

Details & Benefits:

• Tungsten weight - Enhanced draw bias by placing 14g weight (included 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.
