Oban CT-100 Golf Shaft Review

Shamida / Oban CT-100 Golf Shaft Review

The OBAN / Shimada CT-100 is a lower weight version of the CT-115 released last year. They give the club builder the ability to fine tune set stiffness in a constant weight, taper tip design. Iron shafts have traditionally been parallel or taper tip. I wrote an article, Parallel vs Constant Weight Irons Shafts, explaining the differences several years ago. The CT-100, like the CT-115, is a set of 12 constant weight shafts from which the club builder selects a group of shafts to build to an exact the stiffness range. This combines the best aspects of constant weigh taper sets with the tunable stiffness of parallel iron sets. This overcomes the tip stiffness compression inherent in parallel iron sets. If you did not understand that statement, read the technical article.

The discussion about the CT-100 starts at the 9:30 mark on this video shot at the 2018 PGA Merchandise show.

Lets take a closer look at the OBAN CT-100.

ACCRA Tour Z RPG 400 Golf Shaft Review

ACCRA Tour Z RPG 400 Golf Shaft Review

ACCRA added a new profile to the Tour Z RPG in 2018. The Tour Z RPG is a lower launch version of the Tour Z RPG 300 reviewed last year. This video, shot at ACCRA day at the PGA merchandise has Ken Thompson of ACCRA explaining the RPG shafts to the club fitters gathered there.

ACCRA has moved some of their manufacturing to a Japanese foundry. The Tour Z RPG is a made in Japan product. It uses high modulus materials with the lowest resin content of any ACCRA shaft. A new material with a quad weave runs the entire length of the shaft. The 4 Tour Z RPG 400 shafts have consistent bend profiles. Fitters can work to find your proper weight and flex knowing each of these shaft have exactly the same bend properties. The radial consistency was 99.3% with a 0.5% standard deviation. They are round.
