Shaft selection for fast swing

[chandldj]

I have a club head speed of over 100mph... i'm looking at a driver with a Accra T-50 M4 shaft ... i'm told its "stiff flex" and it weighs 52grams... is this a good choice for me?

Thanks!

All things considered a stiff flex from one manf is not the same as a stiff flex from another manf what you need to do is have the flex checked on a freq meter and then plot it on a graph for its length that will tell its actually a stiff or a regular or an extra stiff. then you will know for sure what it is.the other way is get the freq and then send me the freq and the length and I'll do it for you.
