10/12/2019 Golf Driver Shaft X Flex Swing Speed Chart
The proper shaft flex for your swing speed helps produce the optimal trajectory for your shots. Flex Chart: Use the Charts below to determine the proper flex. The charts below are for consistent carry yardages only (don't include roll).
Hi all, As in the title, what 7-iron swing speed equates to a stiff shaft? I have been to two fitting centres in recent months and been measured as a 7-iron swing speed of between 75-80 mph.which both centres stated was regular. I was watching a vector session the other night and the pro, who was knocking a 6-iron nearly 200 yards had a swing speed of 83mph and he was using a very stiff shaft! Is it really a case of a couple of miles per hour makes.that. much difference when it comes to shafts??
As well as swing speed you'll need to bear in mind your height.If you need lengthened shafts you MAY need them stiffer than would normally be the case to stop the club feeling like a brick on a licqourice stick.My Mizuno MP30s are 2' over standard length with a stiff shaft and Mizuno fitted lighter swing weight heads to avoid this problem.My advice is to get the clubs custom fitted, many manufacturers do it free or take the cost off the price of set of irons if you order them. It's well worth it. OK - here's the reason I am asking this question.Those who fllow my posts will know that I have been fitted by two different manufacturers in recent months.Primarily based on the stats from one of these, I purchased a set of their irons (also somewhat enticed by a stonking promotion)My existing 7-year old Mizunos have a S300 shaft in them, yet both fitting sessions spec'd me as a R300Anyway when the new bats arrived, I instantly noticed a problem on the course. I was consistently hitting a club, if not 2 more than I had previouslySo what? I hear you ask.Well, the Trackman stats of this particular 'fitting' showed figures some 20 yards superior to the other fitting and to a recent independent fitting, indicating that I should have been hitting these a club.further.
not 2 less!! Pasty wrote So, you've gone from S to R based on recent fittings. Based on 75-80mph I would suggest that is fine so I wouldn't worry about that.Just to summarise what's happened, you've had a few fittings, and on the basis of one of them bought some clubs which are giving you a couple of clubs LESS distance.My 2 questions to cover the bases would be:1. With the fitting that persuaded you to order the irons, did you use your Mizunos as a control (as you did with an independent fitting)? If not, that's where the problem could be, and as you suggest, the results could be misleading.2. The fitting (what went with the order) recommended R300, did you get R300 with the order or did they swap for another shaft (maybe hence the great deal)? Pasty,I did take my old clubs to the second fitting, but the guy only got me to hit a couple of shots as a warm up and never measured them on the Trackman!I did get the R300 (at least that's what the stickers on the shafts said) and the deal was to do with a promotion the company are still running.The problem with the fitting (apart from the obvious) is that the range markers weren't very prominent and the custom fitting bay was at the very end of the range, hitting to the very edge of the measured area, which was partially obscured by a copse of trees.
This made it very difficult to accurately gauge carry distance. Why all of the talk about swing speed and shaft flex? I thought that there was more to it than that, ie transition, tempo and preferred ball flight.As for believing the flight monitors???????? Unless you are using your own clubs with known distances then I wouldn't believe them. I would be willing to bet that the 'operator' can input certain constants, for eg temp (warmer = longer distance), wind speed and direction (10mph wind behind giving more distance), altitude (same again).Would a salesman be so dishonest to manipulate these numbers to get a sale???? Surely NO salesman would do sucha thing. Not sure about a 7-iron as i thought most club manufacturers tested you witha 6.i currentl;y use mizuno mx 25 with a stiff shaft and will carry my 6 iron 160-165 pretty consistently.
When i was fitted for theses clubs i had a swing speed of 88mph which the guy fitting me told me was almost into the x-stiff category.i was at mizuno 3 days ago, my swing speed is now 84-85mph and they told me that i was on the border between regular and stiff. The moniter also showed that i was carrying teh ball considerable further than i would have expected and one shot even showed me carrying the ball 179 yards which IMO is a load of bull! I couldn never hit a 6 iron that distance. swing speed is not the only variable in deciding the shaft stiffness i must add that theses were 2 different fitters. JC I tend to agree with you. If ur shafts are too soft (ie ur new sticks) you will hook/hit it all over the place!I thinks its all about what right for you.
I was fitted at Mizuno National fitting centre in Wrexham and they were supurb. Started hitting 5-6 shots with my old 6 iron 165yds then selecting a range of shafts based on that. Went for the Rifle stiff in the end as most consistant 6 irons I have ever hit! Old reg shafts a little inconsistant!If you have played mizuno in the past I strongly recommend going to the closest NATIONAL fitting centre for a session (free). Take both sets and they will tell you if any good!I believed the monitor they used as the ball landed were the monitor said it did! IE if said straight wen striaght and distances looked about correct. I asked the manager of Nevada bobs of he sets his swing monitor to show favourable results - he got the right ache. They clearlty had though because at the time I was Mr Erratic with the driver and this monitor had me bombing them down the middle every time. At that time my record number of consecutive fairways found was 1!!!As Clouters joke suggested, the reason we all want stiff shafts is because it makes us think of our manhood. If shafts were not called shafts but something like 'legs' everyone would be happy with regular 'legs' and would not be so keen on stiff 'legs'.
Its an ego thing.
