UST-MAMIYA ATTAS-JACK(11) shaft with TaylorMade sleeve. Flex 5X is a light-stiff shaft, and is praised for its light feel in the hands, allowing the head's weight to be felt, and making it easy to swing sharply. 5X is a popular light-stiff shaft right now, and there's talk that it's easy to switch to 5X if you're tired of 6S and want to reduce weight. However, how it feels varies from person to person. It's also praised for making it easy to create a pause at the top of the swing. In the impact zone, it has succeeded in creating a behavior where the head faces upwards, which was not present in previous models. - Brand: UST-MAMIYA - Model Name: ATTAS-JACK(11) - Features: TaylorMade sleeve Stiffness: X (Extra) 5x Size: Approximately 113cm (grip end to sleeve tip) Sleeve: For TaylorMade The grip is still usable.
