WTD - Stiff Flex 3 wood shaft for Titleist 910F

[philly169]

I've got a 910F which is currently a regular shaft, and I can feel the flex in my back swing, so looking to change it to a stiff flex.

Anyone got anything? Needs to have the Titliest adaptor.

I have a kaili stiff shaft for a 910 if interested
