You can tell the stiffness by the amount of dots after where it says " #1 in tour distance". Look into it, do a search... I remember that from when they came out.
Mine is an X flex and has 3 dots. I still have a spare one, might put a g30 adapter on it.
LB...u are correct in the shaft being spineless...I have 2 of them and they show nothing.
