This shaft was originally for a SIM MAX driver, but I've been using it with a Qi10 as well. I've been using it for about 3 years, playing on the course about once every two months and going to the driving range about once every two weeks. I've replaced the grip once, but there's some wear and tear from use. Please check the 6th photo, although it might be a little difficult to see. I plan to ship via Rakuraku Mercari. - Model: TM 50 - Flex: FLEX-S - Loft Angle: STD LOFT - Right-handed: RH - Shaft Diameter: .335 Thank you for looking.
