no difference in distances when changing shaft flexes

[moonducks]

hey guys,

i tried out the same 7 iron in R, S, and X flexes at a hitting bay the other day and they were all going very similar distances (between 170-180) at 85-90 mph ss. i thought as you go up in flex the distance should get lower (and yes dispersion was obv better with the stiffer flexes). I was trying the Mizuno JPX 825 Pro forged irons

what's going on here?

Why would the distance get lower as you go up in flex? If you can swing it the same speed, control it, and hit the sweet spot the ball doesn't know what flex the shaft was.

almost everywhere i read says you will lose several yards if you go up in flexes. but i guess your right...if im swining it the same speed it shouldn't change

Generally speaking, ball flight is what is effected by flex, which in turn can effect distance.  For example, if you have a slow swing speed/slow tempo and use a stiff shaft, you might hit a pretty low ball that doesn't carry as far as softer shaft that would fit your speed/tempo.
