Mitsubishi Kai’li – The Next Engineering Evolution

We first saw the Diamana Kai’li at the PGA Merchandise Show in January. Everyone gathered around the Mitsubishi area was absolutely buzzing with excitement at this latest offering from the company.Translated, the name means “blue diamond” and the design is for the more advanced golfer and gives them more ball control. An ultra-thin, multi-layered carbon fiber material makes up the shaft – all engineered at Mitsubishi from start to finish with a technology called MDI. This is the “multi-dimensional interlay” that strategically positions multiple layers of their proprietary ultra-thin material at multiple andles of orientation through the entire shaft.

We found buzz about the shaft saying, “The Kai’li has a multi-dimensional design that utilizes thin sheets of carbon arranged in a multi-layer structure to control torsional stiffness, stability, and elasticity. A mixture of unidirectional carbon fiber for stability coupled with high elastic modular carbon fiber make up 68% of the shaft. The result reinforces the shaft for control and dispersion while still giving it elasticity when storing and releasing energy during a swing. The Kai’li is available in 60, 70, and 80g ranges with lower torque and mid-high kickpoints. The kai’li is designed to give harder more aggressive hitters the confidence and control they look for with a low to mid trajectory and a low spin shot.”

The finish on the Kai’li is remarkable in itself. This is what each angle of one shaft looks like – the color changes as you turn it:

The company touts a smooth, precise profile with stability and consistency during swing loading and unloading. This has a slightly firmer tip with less torque than the original Diamana Blue Board.

Spotted: Titleist GTS USWO headcovers

GolfWRX Tour Photographer Greg Moore was at Riviera Country Club this last week in Los Angeles for the U.S. Women’s Open. While browsing the photos, I spotted a recent major trend in headcovers. That is, the Titleist GTS headcover line expands the majors theme.

Seen on the bag of Natalia Guseva were the red, white, and blue Titleist GTS covers. This is the third time we have seen limited-edition Titleist major covers, the others being at the Masters and the PGA Championship. But with the launch of the GTS line back at the Texas Children’s Houston Open in March, this is the first time we have seen Titleist come out with major themed head covers for the season (driver headcovers through hybrids).

Check out some photos below.

At the Masters, we saw the familiar Masters green, white, and yellow. While the PGA Championship design was colors synonymous with the Philadelphia Eagles NFL team. This shows the season major drops continue full steam ahead for major OEMs. New opportunities for each major for designs and themes, and who knows, maybe a lucky spark for a player and a major championship for their resume. It gets the wheels turning for what major theme headcover you would keep on your bag for the whole season!
