Mizuno DNA Shaft optimiser

[Stuey01]

So I am in the market for some new irons.
I will be buying Mizuno, and I will almost certainly be getting MP64s.
I've hit the demo 6 iron a couple of times on the range, with a DG S300 and a KBS tour stiff. I couldn't tell a great deal of difference in the two, and was fine with them. Both brought my mega high ball flight down a bit, which I liked (currently playing dynalite s300 and hit the ball so high).

So I had some time yesterday and popped into AG, hit the 4 and 6 iron into a net, with DG s300, and seemed to be getting decent contact, love the feel of these things. Also hit the MP53 with a DGr300, I could not hit this thing consistently at all.
I went through the fitting steps with one of the guys, standard length (I'm 5'10), ping chart says 1* upright, but the strike board suggested no adjustment needed.
Bunged a KBS tour stiff on the 6i demo club and really liked it.
I had a go on the swing DNA, measurements were 88mph 6i average club head speed, 4 tempo 4 toe down 2 kick angle, 5 release factor.
So it comes up with my shaft recommendations:
x100 (soft stepped once), px6.0, xstiff KBS Tour (soft stepped once)
I'm gobsmacked by this. The guy fitting me was surprised also, he was expecting a range of standard stiff shafts.

I am on the verge of placing an order but now torn between a straight in KBS tour stiff versus a soft stepped KBS Tour Xstiff.

Anyone else got any experience of this swing dna?
What about a kbs tours stiff versus a soft stepped xstiff?

I'm erring toward the standard stiff, I'm a little worried an XS, even softstepped, would be like rebar.

I wouldn't trust that DNA thing at all. That said if your swing speed is 88 mph then I'd be quite confident you could handle x100 & px 6.0. I hate KBS so can't comment.

what FELT best and gave you a consistent FEEL?

Swing DNA is not a fitting. It is a good starting point for one, though and the shafts suggested need to be tested for feel, flight and shot shape, and the choice adjusted accordingly. However, I personally would not rely on the quality of fitting at AG and I certainly wouldn't buy without hitting your chosen shaft in the open air..

If their figures are correct, you are between Stiff and X flex. 88mph is a good swing speed for a 6 iron, so that is credible.

Soft stepping takes the flex down about 1/3 of a flex, so there is another point between S and Xss1, which is Xss2; X soft stepped twice, which should be the same as S hard stepped once!

How so? Have you had a poor experience with one?

 

[Imurg]

My numbers were 84mph, 4, 2, 4, 4 and it kicked out S300, PX 5.5 or KBS stiff

Real differences are Toe and Kick - I don't really know how to interpret the figures but that may well be why it's given you more X-stiff shafts....
The Mizuno DNA isn't foolproof and it's also not the "letter of the law" - the Pro should be able to look at your ball-flight and pick the best as well as looking at numbers. The DNA is only really a starting point.

 

[Ethan]

Swing DNA:

Swing speed - obvious
Tempo - 1 to 9, slow to fast
Toe Down - amount of flex in that plane. not a big deal
Kick Angle - shaft bend towards target
Release factor - early to late. Later needs stiffer shafts

So the OP is 88mph, 4, 4, 2, 5. Of these the tempo and release factor are in the mid range, so when taken with swing speed put him on the border of S and X.

Imurg, on the other hand, is 84 mph, 4, 2, 4, 4, which corresponds to a set of Jessie Valentines with lightweight ladies shafts!











OK, that was unfair, standard stiff shafts.

 

[Stuey01]

Thats interesting, thanks Ethan.

Is the midrange tempo and release factor causing the assessment to go up from S to between S and XS, or down from XS to between S and XS?

I suppose the conclusion I need to draw from this is I should pony up the £30 for a full iron fitting using flightscope, proper balls and a PGA pro at the range.

Probably neither in terms of up or down, just kinda in the middle on swing speed and tempo and release not moving it definitively one way or another.

I would pony up the £30.

Unfair - bordering on the libelous yer steamin' great Mod you!!:ears:

The craw is right, dont go with the DNA thing unless you're going on Jeremy Kyle.

I would also take care with the KBS stiff shafts. My mate who plays off one, hits a strong ball, has always played stiff shafts. When being fitted for his 58s he got more from the reg KBS than any other shaft.

Go without any preconceived ideas, and don't get caught in the headlights. It's too easy to buy what you like, I try to like what I buy, If you know what I mean.

Brilliant - this whole thread was a foreign language but stuck with it and got my reward at the end :thup:

 

[CMAC]

WTF is Pony up?

 

[Scottjd1]

I went with the full Mizuno fitting, I think its good to point the fitter to a good start for shafts and flex and then look at ball flight and adjust accordingly. I ended up with the 3rd choice but it was close between that and one other that wasnt an automatic recommendation.

Worth the money.

Sadly not OLD enough.....!

KBS seem to get different responses in different people. I used KBS stiff in MP68s and thought they were pretty smooth. Your mate must be a good enough player to be able to play with a range of flexes.

They were designed by the same guy (Kim Braly, hence KB) who designed Project X and intended to be like Project X (mid launch, flattish trajectory, lowish spin) but with feel.

That would be £30 well spent imo.

As posted previously, Swing DNA really only measures a few extra attributes so shrinks the wide range of 'available' shafts down to a few. The key is then trying those and deciding which feels best.

I would have thought KBS C-Tapers (maybe hard-stepped S or soft-stepped X) might have been an option also, but they may not have been in the 'available' list. Nice (and pretty) shaft that I actually preferred to my KBS Tour S - that still felt nice.

 

[Stuey01]

I think you guys have convinced me to splash out 50 notes at the Mizuno national fitting centre in London. I'm not sure I trust the local chaps at the range and the experience of the national fitting centre sounds really cool.

There was a dispute between Mizzie and KBS on the economics of the CTapers, hence why they weren't included in the DNA options. I thought I heard it had been resolved so don't know if they are available as yet.
