Mizuno is making a serious push in driver design with the JPX-900. By adding loads of built-in adjustability, power and forgiveness, it's clear that the company wants to be known for more than its irons.
For starters, a new multi-thickness face design increases the area that produces high COR (0.800 or more) compared with the JPX-850, for added ball speed on hits toward the heel and toe, as well as high and low.
Players can also boost performance by placing two eight-gram sole weights in the heel or toe or along the center rail. Manipulating these tungsten-steel weights enables you to fine-tune launch angle and spin rate and create fade or draw bias. The 450cc head also has an adjustable hosel (-2° to +2° loft) for additional launch and spin control.
There's one more adjustability feature: A silver aluminum disc on the sole helps change the face angle at address up to 4°. Sliding the disc forward rotates the head closed, while moving it back causes the head to set up more open). For example, the face angle in the 10.5° head ranges from 0.75° open to 3.25° closed. Lastly, internal ribs along the crown and sole contribute to a strong impact sound while maintaining overall durability. Comes in 9.5° with the company's adjustable loft system (set it between 7.5° and 11.5°), and a 45-inch Fujikura Evolution II shaft. $500.
Complementary JPX-900 fairway woods ($300 each) and JPX-900 hybrids ($250) round out the line. The JPX-900 series will be at retail starting September 16.
