Product: UST Mamiya Attas 11 shaft

Pitch: From UST: “A revolutionary combination of innovative shaft design and advanced carbon fiber materials. We combined aerospace grade M40X Carbon Fiber with a new constant taper design. Designed for a higher launch, high performance shaft offering optimum flex and torque characteristics with feel. The ATTAS line has been a successful staple in UST’s offerings, and with the introduction of ATTAS 11 or “Jack,” this will be no exception. Designed to improve launch, but keep the stability the line is known for, this rendition enhances the line with better materials, better energy transfer, and an unforgettable feeling swing experience.”

Our take on the 2020 UST Mamiya Attas 11 shaft

I was provided the Attas 11 6S weighing in at a raw weight of 66 grams, 3.8 degrees of torque, and profile promoting mid-spin with a mid to high launch. This shaft was placed in a Wilson Staff Cortex head playing 11 degrees with the weights in the neutral position and the sliding weight in the middle front location. The shaft was placed up against another UST offering: the Helium, which is a shaft that has been very popular and notable for its lightweight, but super stable design. I was also able to hit it against the Fujikura Atmos Blue Tour Spec 6S.

On course testing went right along with claims from UST. I experienced a good mid flight with notable lower spin than the Helium. The Attas 11 felt much stiffer than the Helium but not in a negative way. After a few rounds with “Jack,” I was impressed with the consistency I was getting in flight, control, and distance. My miss was predictable and controllable, whereas I have been having more of a two-way miss with the lighter Helium.

During an analysis at David Ayers’ Low Country Custom Golf with fitter and club guru Kristian Barker, we discussed shaft profiles and recorded some numbers to see how they compared. The first round was very subpar in terms of swing and after a round with all the shafts and a little guidance from Kristian, the second round was much better. I was very happy to be able to have a testing day where I can see how the equipment performed with bad and good swings.

The Helium was the distance winner, but even though the offline number portrays better accuracy, I was having my typical two-way miss with both left and right big misses. The “Jack,” while a little shorter, gave me a consistent ball flight that was more likened to how I hit when I’m playing well. Also, though the Helium was a bit longer, that can easily be attributed to the fact that it is much lighter, and after the session, I measured it at 45.5 inches playing length whereas I had the Attas 11 cut to 45.

Overall, the Attas 11 is certainly a premium shaft that caters to those who would like a little higher launch without worrying about the spin getting too high or feeling overly stiff. On course and the launch monitor, this shaft performs and is every bit of what UST has marketed it to be in terms of launch, spin, and feel.
