Mizuno DNA Shaft optimiser

Indeed, Wishon thinks it softens/hardens the flex slightly. You 'quoted' me before I added the query re CPS numbers on my previous post.

PS You still seem tetchy! :confused: Same side of bed as yesterday?:D Mod responsibilities? ;)

Not tetchy. Just getting to the point.

Would that others (not you) would do the same.
 
Can I ask a question on the swing DNA?

Seeing as I'll be using one in the near future, what shaft is your swing tested against?

Current shaft? Prospective shaft? Iron bar?

Well, he didn't even say whether he agrees or not, so his rather vague exaggerated statement is rather unhelpful.

The modern media technique is to set up debates suggesting they are finely balanced, with one proponent and one opponent. You see these arguments about climate change and stuff like that, even when the overwhelming majority opinion is on one side.

I have never heard one credible golf pro saying that soft stepping or hard stepping does not achieve the flex change intended. If MGL can point me to even a few references that do, I will happily read them.

I'm not sure why you are so tetchy about it tbh. Also, I don't want to distract and go off topic from the OP so will perhaps set up another thread at some point.

So do you think soft and hard stepping works or not?

I don't know why you are so evasive about it.

It is relevant to this thread because soft and hard stepped shaft recommendations are made by Swing DNA and if you have some insight to offer, it may inform the OP and others.

I see.

You get your "speciications" from their own "standard" shaft then progress on. Makes sense now.

Thanks for that SB :thup:

If it was interchangable I think it'd be impossible to calibrate. Although, going by other's comments it seem that it isn't that well calibrated in the first place.

When i had a go with it, the 3 swings were so bad the little screens said " find another hobby" :)

I did wonder why I was recommended a set of darts...

I think its an excellent piece of kit personally, if used a guide. And that's the important phrase, "guide". The pro should use the shaft recommendations given, fix on a head that you/he want to try and see the results, both in flight and on the monitor. Nothing to stop the pro and you trying other shafts though.

I had mine done at England National fit centre with a fitter that knew his stuff. I've had other fits elsewhere (e.g. shop/ranges) that just don't do a full enough job.

Enjoy! :cool:
 
Don't get me wrong Piece, I thought my fitting was terrific. I'm a high handicapper, so it was always going to be a bit of a rough guess as to the shaft that best suits my ever changing swing. I'm very happy with the shaft I have (Nippon 950GH reg flex).
 
When I had a fitting for my MP59's the DNA shaft optmiser recommended Project X 6.5's, KBS Tour extra stiff and X100's, my clubhead speed was 96mph with the 6 iron. So I tried all 3 and to be honest there wasn't too much difference between them. Then my fitter threw a Nippon N.S. Pro 1150GH Tour stiff shaft in for me and I gained 10 yards of carry without any loss in dispersion and they felt much better.

So in my experience it's not 100% accurate. It's all down to the player though, I'm sure people with similar swing speed/tempo to me would not get on with the shafts I went with.

Those 1150s are slightly softe than the (1150 X) shaft that another fitter used to 'match' a head only wedge to 2 the other (Y-Cutter) wedges that were alread shafted with PX6.5s.

Way too stiff for me to use in irons, but ok in wedges. Had some 1150 Ss in a set of VIP blades - and matching wedges. Irons were too much, but I really regret selling the wedges! :angry:

Entire key to this fitting malarkey seems to be to get close first, then try the different styles to see what suits best - both for the stats and the player feel. While there are precision instruments involved, I don't believe fitting is an exact science!
 
what a shame - a thread that started so positively and informatively .....

"The DNA system is flawed in my experience, it said my mate need regular shafts. He was off +3 and had just turned pro at the time. He and the club maker ignored the DNA and he ended up with a choice of X100 or KBS Tour X. "

No real evidence of 'flaw' - we all know Luke plays S300 and he's a little better than +2; he's also well beyond the ego frequently associated with many for whom such stiff shafts are seen as an indicaor of their (high) capability.

Equally the DNA system is limited in it's absolute recommendations - it's a better starting point to where to focus and why than swing speed alone. It's also a 'quick and cheap' way to get an indication of whether you are likely to find a significant benefit in taking things further (as it clearly did for Stuie) or if the money, and time, or if the route to progress is more aligned to R and lessons (these people do exist in the real world).

True dat.

it has been said at least 10 times in this thread that Swing DNA is just a starting point for a fitting, not a fitting.

Also, highly skilled players have a much wider tolerance for what equipment they can play. I have seen Michael Campbell play a ladies flex driver and he hit it exactly the same as his own X shaft version. Smooth repeatable tempo is a great thing.

The DNA monitor is fixed on their apparatus shaft. It's a normal 6i.

Had a session this afternoon as I am toying with the idea of some new irons. Was very surprised with the suggested shafts.

On reflection, the best shaft I hit all day was the one the DNA gizmo was attached to. Lovely high, long flight with a touch of draw!

Wish I'd asked what it was!
