Hzrdus Black 75 driver shaft

[griffgolf]

Does anyone know what the difference is between the 6.0 stiff flex and the 6.5 X-stiff flex " Hzrdus Black 75 " driver shafts as when looking at the specs the weights, torque etc are all the same? Here is a link to the specs and they are the same for both shafts HZRDUS Black - Project X (truetemper.com)

Flex is just a way of matching the shaft to your swing speed as it says 6.0 is stiff and 6.5 is extra stiff. Torque is a measure of how much the shaft twists in the swing and I would expect it be the same for the same shaft regardless of flex.

If you are looking to match the shaft to your swing just do the shaft fit on the page as a starting guide.
