In early March I bought a set of used Mizuno JPX 825 irons with stiff graphite shafts.  On the day that put the Mizuno irons in play my index was 8.7.  After playing the Mizuno irons for a few months my index is 11.92!  Coincidence?  Hmmm, don't know.  I do know that anytime I tested graphite shafted irons vs. steel on my skytrak the steel shafted club data showed lower dispersion.  There are other factors involved of course like the variability of my game but the 8.7 index was at a time of year when my index usually goes higher.  

Anyway I took the Mizuno irons out of the bag last night and I put the XHot steel shafted irons that I was using previously back in.  It will be interesting to see if there is a downward index trend.  Regarding how the Mizuno irons played I really like them and they are easier on the old joints.  I did notice that I seemed to be hitting more balls over the green then I was with the steel shafted XHot irons.  Maybe the graphite shafts actually are less consistent on mishits vs. dead solid hits.  Yes, I do 'nuke' one every now and then LOL.

If there is actually a performance difference I probably would not have noticed it based on my impressions of the clubs while actually playing.  Possibly a case of facts vs. feelings.  For me knowing the difference is something that requires some statistical analysis.  Makes me wonder how many times average golfers put new clubs in the bag and think that they are doing better when in fact they are doing worse.  At any rate once I get my swing mechanics stabilized I am planning to go and get fit by somebody who can really figure out what head, shaft and grip combination will work well for me.  Should be fun!

Frank mentioned a few days ago switching back to steel shafted irons and picking up some distance which is interesting.  What is your experience regarding steel vs. graphite iron clubs?

I'm not too old yet but my joints hurt now and then and I have a little arthritis in my hands and neck.  I don't think I'll ever go back to steel, because the same mishits that I can't even feel with graphite shafts hurt like crazy, or are at least unpleasantly bone-jarring, with steel.  For that matter, even shots hit fairly close to the sweet spot don't feel great with steel to me.  Granted, when I play with steel (rarely) it tends to be someone's 20yr old set that I'm using as a loaner when out-of-town.  So maybe a modern game improvement set of irons with new steel shafts and some kind of vibration dampening in the shafts or grips would make me think differently.  But I doubt I'll ever invest the time/$ to find out.  I'm happy enough with graphite. I have many flaws in my game but I don't think I can fairly blame them on using graphite.  Edit: I use R flex graphite on all clubs, woods and irons.  I've tried stiff flex graphite in woods/driver and I don't like the stiff flex graphite feeling either -- also too bone-jarring for me. If I hit the sweet spot more often I probably wouldn't notice, but alas!

I wouldn't be surprised if the Mizuno faces are a bit hotter.  The lofts are a little weaker than your X Hots, although they are both modern-strong.

My experience is that I hit steel irons a little farther because the heavier weight complements my natural tempo and tendencies.  It really helps me stay on plane.  I don't find graphite to be wilder in its own right, but wilder because it fights my swing a bit.  Shaft weight is probably the most important "preference" variable in getting a good fit, I think. 

I would love to see 100 gram graphite shafts with regular or senior type flex profiles.  Today's heavy graphites are very stout.  Hireko sells some old piece of junk that's heavy, but it's an old piece of fiberglass junk.  For now I'm sticking with steel, but my joints will be upset soon enough.

I have a set of Mizuno JPX 825 Pro (forged model) that I've played for several years and really like them. They are steel shafted and I feel like I need to go to graphite. At almost 72 my joints are starting to let me know. Just not sure what I want to hit now so, like you, I will probably go to a fitter and see what they come up with. We have some pretty good ones around here. Only fitting I've ever really done was at Edwin Watts for a set of Pings way back when the G2 came out. Those were nice clubs too. Anyway, if you can play steel and not have any pain anywhere I would stick with it.

"I would love to see 100 gram graphite shafts with regular or senior type flex profiles." 

Don, there is a shaft out by Aerotech called Steelfiber i95. It's a graphite core shaft with very thin steel wound fibers on the outer surface. Weighs in at 95 grams. I hit a friend's P790's shafted with those and they are very good shafts. I'm not sure of the cost but probably a little on the pricy side. Anyway, that's what I'm thinking I will get in my next set of irons. They also make it in a 110 gram shaft, I believe.

Aerotech shafts have really good reputation.  I have one but have not installed it in anything yet.  They are expensive.  My understanding is that a lot of pros use them as they have better dispersion then most graphite shafts.  Seems to be one of those deals where you get what you pay for!

I have a Steelfiber 80i or i80 shafted 7 iron.  I like it.  Everything I've heard about the 95 and 110 is that they are very stout.
I demo'd a set of Mizunos with the Recoil 95 in F3 which is R flex.  They felt too stout too.  

Yet I can play fairly stiff steel and it feels good.  So who knows.
