Anybody use a Stiff Flex Driver but Regular Flex Irons?

I'm just curious how many of you use an S-flex on Driver and/or Fairway Wood but R-flex irons?

Also, what you do about Hybrids?  Do you use the same flex as your irons, or the flex of your Driver and Woods?

I use stiff flex in my woods and hybrids and regular flex in irons and wedges. My regular flex is 110 gram shafts so they are not exactly light weight and thats what probably works for me. I do not see the need to change the shaft on my set at all. I think if a regular shaft is heavier it may not be that wippy compared to a regular shaft that is light weight. My swing speed with my driver is 105mph average and that means I should use stiff flex in my irons too. But I hit the ball high (which I like) with my regular shaft without it being wippy due to its weight. So for me it's a perfect combination:-)

I have S-flex in my Driver, but my Hybrids and Irons are a Firm flex.  Ultimately, the flex I use depends on the shaft.  My previous set of irons had S-flex shafts in them because that shaft tended to play a little softer.

My Callaway FTiz driver is a Project X 5.0 graphite shaft, which is rated at Firm, between Regular 7 Stiff.

My Callaway FTiz 3 wood is rated stiff

My Callaway FTiz #3 & #4 hybrids are rated stiff.

My Mizuno MP-53 irons, 5-PW are Project X 4.5 graphite which is rated at Regular.

Lately I've been using an X flex driver and S300 irons.  The irons have a swing weight that gives me better control than I lose through the flex over the X100s.  Plus I can really feel the shaft load well so it's helped when working on my swing.  My swing is a little longer and smoother these days, so my loading profile is different than it used to be.  For me, overall weight and swing weight are by far the most important factors in irons.  I want maximum responsiveness so that my body can sense what's going on with the club.

My irons are steel. So does that mean it's stiff?

I hope so.

These are my clubs.. any help would be great.

I use a reg-flex driver.. but i was naive.. i feel as though a stiff would be better.

If your clubhead speed warrants a S-flex driver, you'll need the same flex through the entire set.

it's not unheard of to go s flex woods and regular flex irons. driver swings can be an entirely different animal than an iron swing and the speed difference doesn't necessarily transition at an exponential rate.

with your handicap you might be smooth as glass and step down swing speed accordingly, but for a higher handicapper your irons might be way slower than your driver and you might lose distance getting stiff just based off of your driver swing for your irons.

as for the OP, i use R flex irons and an S flex driver, 3w, and hybrid. i'm getting fitted for irons tomorrow so i'll let you know what they recommend (not that it has any bearing on you, but just for another opinion/experience)

i don't draw the club back very far with my irons, especially compared to my driver so that might have something to do with it.

Edit:

i will also add that i had all R flex and each fitting i've had so far has bumped me up to an S flex which has given me much straighter and more predictable ball flight, so i could be all S flex, but i'll give you the results tomorrow.

My driver has a stiff shaft but my irons are regular.  That came about because the irons were bought two or three years later than the driver, and though I worked with a professional on the choice of irons we did not use electronic equipment.  However, both driver and irons do well for me (I have a 7 handicap).

But the nagging feeling has been in my head for a while that maybe I could get extra distance with another shaft and a more recent club.  So, last evening I had a fitting for the new Ping Anser adjustable driver.  I told the fitter, who was excellent, that I thought I should have a driver with a regular shaft.  He switched me between stiff and regular shafts, different makes of shaft, and changed clubheads to try a variety of lofts.  None of these changes made any significant difference to the readings from the monitor.  Not clubhead speed, launch angle or spin rate.  And I was achieving exactly the same range of distances with a stiff shaft as a regular.  To add to the mystery the new club was no different in readings than I was getting with my TaylorMade R7 which is about 5 years old.  Maybe the new club would be slightly more forgiving (it has a wider face), but the difference was minimal.

I departed mildly unhappy that there was no magic formula for increasing my distance but also more than mildly happy that there was no point in spending almost $400 on a new club.
