The Tensei CK Pro White is the latest release from Mitsubishi Rayon Composites (MRC), a low-launch, low-spin shaft with a multi-material design that the company says improves the performance and feel of the shaft. Whereas most golf shafts use between 3-6 different materials in their construction, the Tensei CK Pro White is made from 11 different materials, giving MRC engineers greater precision in the shaft’s design.
Like MRC’s Tensei CK Pro Blue shafts, which produce a slightly higher-launching, higher-spinning ball flight, the CK Pro White uses MRC’s Carbon Fiber DuPont Kevlar Weave in the handle section of the shaft. The company says it increases the strength and stability of that part of the shaft, leading to better feedback.
On the other end of the shaft, the tip section, MRC uses a boron-reinforced fiber. All low-launch, low-spin shafts have stiff-tip designs, but the addition of boron puts the Tensei CK Pro White in a class of its own when it comes to lowering launch angle and spin rate. The boron fiber also reduces torque, which can offer better energy transfer, more accuracy and better feedback — especially for skilled, high-swing-speed golfers.
Connecting and reinforcing those areas of the shafts is MRC’s low-resin content (LRC) prepreg. Prepreg is carbon fiber that’s been reinforced or “pre-impregnated” with resin, a glue that holds the material together when it’s formed into sheets and rolled into the form of a shaft. MRC says that its LRC has 15 percent more carbon fiber and 13 percent less resin than traditional prepregs, which allows MRC to make the Tensei CK Pro White stronger without adding extra weight to the shaft. MRC also uses high-modulus, 40-ton prepreg in the Tensei CK Pro White’s design, which like LRC is thinner, stronger and lighter than traditional prepregs.
In the EI chart below, you can see how the Tensei CK Pro White’s bend profile compares to the CK Pro Blue. The main differences are its slightly stiffer tip and mid sections, as well as its slightly softer butt section. That gives the CK Pro White a higher “kick point” than the CK Pro Blue. Generally, the higher the kick point of a shaft, the lower its launch conditions. That’s why the Tensei CK Pro White is a lower-launching, lower-spinning shaft than the Tensei CK Pro Blue.
Just how much lower launching and lower spinning is the Tensei CK Pro White than MRC’s latest premium driver shafts? I put it to the test against the company’s Kuro Kage XT and Diamana BF-Series, which like the CK Pro White are PGA Tour-quality shafts that sell for about $400 each. All three shafts tested were built to my spec: 70TX, tipped 1 inch at a finished length of 45.5 inches.
I tested the three shafts on Trackman 4 at the Launch Pad at Carl’s Golfland in Bloomfield Hills, Mich. After warming up, I hit 10 drives with each shaft, and whittled my shots down to the most similar five to help illustrate the differences. Premium balls were used for the test, and results were normalized.
As expected, the Tensei CK Pro White was the lowest-launching, lowest-spinning shaft in the test. That’s impressive in its own right, but what will really excite golfers when they try a Tensei CK Pro White is the shaft’s feel. It’s noticeably smoother than the MRC White Board shafts I’ve played in the past. You could likely duplicate the launch conditions of the Tensei CK Pro White with similar products from other premium shaft makers, but I’m not sure its smoothness can be replicated in the category. It’s something special, and I expect a lot of serious golfers with above average club head speeds will be willing to pay a premium for it.
MRC’s Kuro Kage XT uses a stouter iteration of the company’s famed “Blue Board” bend profile, and in that regard it’s quite similar to the Diamana BF-Series. That’s what makes the shafts a little higher launching and higher spinning than the Tensei CK Pro White. The Kuro Kage XT has a much different feel than both, however, due to its use of an elastic wire made of Titanium and Nickel that MRC calls “TiNi” wire.

In the Kuro Kage XT, the TiNi wire is added to the bottom 13 inches of the shaft, where it adds stability, but it also serves another purpose. Its elasticity allows the bottom end of the shaft to better load and unload during the downswing to help improve energy transfer. That’s what gives the Kuro Kage XT its more active feel, at least compared to the boron-infused tip section of the Tensei CK Pro White, which by design offer no elasticity.
The Diamana BF-Series also uses boron in its tip section, and its combined with a new, aerospace-grade fiber called MR-70 to create what MRC says is a first-of-its-kind hybrid prepreg. MR-70, which is manufactured by parent company Mitsubishi Chemical, is 20 percent stronger and has 10 percent more modulus than similar fibers, MRC says. The handle section of the BF-Series is reinforced with MRC’s Pitch Fiber, which functions to boost energy transfer like the CK Pro White’s Carbon Fiber DuPont Kevlar Weave.
In terms of launch conditions, the best fit for me was the Diamana BF-Series. It launched the ball a little higher than the Tensei CK Pro White, and added a little spin to help keep my drives in the air. It was also easier to swing than the Tensei CK Pro White, helping me more easily hit a draw while offering an even smoother feel due to its less rigid tip and mid sections.
To recap, if you need to lower your launch conditions, the Tensei CK Pro White is one of the most intriguing new MRC options to help you do so. Need a higher ball flight? Try the Diamana BF-Series. And if you want a radically different feel, give the Kuro Kage XT a try.
