UST Mamiya introducing new Attas 11 shafts for 2020
UST Mamiya has had tremendous success with the Attas line since its introduction. For 2020, the Attas line getting another update with the new Attas 11 with M40X carbon fiber, for improved feel and higher launch without sacrificing control, according to the company.
What separates the Attas 11 from previous Attas models is the introduction of M40X carbon fiber to improve feel and help increase the overall energy transfer to the ball.
So what is M40X carbon fiber? Lets dig in for a moment…
M40X carbon fiber is a material developed by Toray—a producer of prepreg raw materials carbon fiber. The M40X material is an improvement in tensile strength to previous versions of the carbon fiber—while also increasing the equivalent tensile modulus by 30 percent compared to conventional carbon fibers. Tensile modulus is also known as tensile elasticity, which is the tendency of an object to deform along an axis when opposing forces are applied along that axis.
(Let me see if I can further explain) Generally the “stronger/stiffer” a material is, the less tensile strength it has, meaning its resistance to breaking under pressure actually goes up. If you can make a material not only stronger but also more resistant to breaking when put under stress you can essentially “bend” it more, and the more it bends, the more energy it will store then release.
In UST’s case by using M40X material in the new new Attas 11 it can create a shaft that is stronger while also being more flexible on a molecular level. Another element of the Attas 11 design is a constant taper from butt to tip of the shaft. We see a lot of graphite shaft companies do this with certain models because just like with the utilization of higher end materials, constant taper can improve overall feel.

Neal Shipley was the first to admit that he enjoyed his food while in college. But since his days at Ohio State, he’s slimmed down and earned a PGA Tour Card.
That hasn’t stopped him from having fun with his wedge stampings, though it’s led to some misunderstandings.
On the 54 (degree), we have ‘Big Fudge,'” Shipley told GolfWRX. “It was supposed to be ‘Big Fridge,’ so this happened a little while ago. ‘Big Fridge’ was a nickname between my college teammates and I, with ‘fridge’ meaning stomach, a big stomach.
“We told the Ping guys to put … ‘Big Fridge’ on it, and I think maybe some bad cell service or something, and they thought I said ‘fudge,’ so they put fudge on it.”
On Shipley’s 50-degree he also continues the food theme, this time with his go-to order at the “Golden Arches,” and his stamping “DONS 7.”
“The number 7 meal, the two cheeseburger meal, that was my McDonald’s order, back when I would have McDonald’s frequently,” Shipley shared.

Is this supposed to be a fairway wood shaft?
