What happens if your shaft flex is too flexible/stiff for your swing?

[erock9174]

This year I've had 3 drivers.

I have an 82mph driver swing so right on the bubble of a lite and regular flex shaft in most brands.

One was too stiff and I was constantly hitting it low and to the right (usually either a push or slice).

One was too flexy; when my timing was right I hit it good, but I was spraying it all over including bad mishits.

The one I am using now seems to be a good mix in the middle and its going much straighter and trajectory is good.

the  answer that makes sense for irons.

Too stiiff..lose distance but not direction (unless for some reason one changes one's

swing)

Too soft ...can lose direction...either way... because club too whippy.

Assumes torque is related to stiffness also
