Any thoughts of the pros and cons of flat line frequency parallel shafts versus the standard stepped taper shafts. I wonder why the whole world doesn't go to one or the other if one is clearly superior. I would think the same frequency would make some of the clubs too soft and some too stiff in a set.

it can be a can of worms to open and talk about..

i have seen where the flatline theory has helped senior and women players.. mainly those with slower swing speeds..

myself never really liked the straight line theory...

Tapers, apparently give better feel.

.......interesting subject though. I wonder what others opinions may be.
