Can anyone tell me why the PW shaft would weigh 115 grams, and the 3 iron shaft 105?

No wonder my swing weighting went haywire when I had these shafts installed.

Anyone have more detailed information about these shafts than the promotional ads?

Do the 950s do the same thing?

I know that in graphite shafts, they are some that are constant weighted. The shafts are meant for each head to maintain swingweight. If this is true for the NS Pros, maybe they weren't installed correctly???? :?:

Well, the PW shaft was 35 inches long and the 3 iron shaft 39 inches long, according to the information printed on the butt of the shaft. So, it appears they were installed correctly. Yes?

Sounds as if they are flighted. Lighter long irons for more clubhead speed. Most golfers loose efficency in the long irons and would want this help. Heavier short irons for heft and tempo control for more accurate shots. Sounds like a good set of shafts to me. This is no doubt why Nippon wants their shafts installed by people that know what they are doing and not by people just slapping it into a head thinking everything will be the same as a DG. My guess is that a qualified assembler would have weighed the heads and done swingweights on the clubs with a dry fit and added tip weights to accomodate the lighter shafts.

Good point!

But I have a follow up question. If you add weight to the longer irons don't you defeat the purpose of the lighter shafts?

I guess I'm not really clear on what "flighted" means. Is it weight variances? Stiffness variiances? Or both?

It's odd that they are flighted because their ad says they are "constant weight," as I recall.

Flighted will typically be stiffness (which swingweight plays a roll in) and bend point. You can also flight the weight but if they are claiming constant weight then I guess in this case it isn't. If you don't like them I would love to try them (assuming stiff flex and taper tips here). Drop me a PM if you want to sell the shafts.

Well, after writing Nippon and telling them the following shaft weights with the respective irons:

3, 105 grams (note the huge gap between the 3 and 4)
4. 112
5, 113
6, 113
7, 115
8, 115
9, 115
p, 116

The answer is interesting...

Cameron,

... [W]ho knows what the original purchaser had in mind. When it comes to this type of thing we have hundreds of possibilities of what the original user was requesting. We do so many specialty installations around the world that this might have been exactly what they intended. It is NOT uncommon for a golfer to seek out this exact ascending weight scheme. We have several players on the Champion's Tour and LPGA Tour who purposely have us intall a lighter shaft in their 3 iron or sometimes in a hybrid type club. The intent is to generate a bit more club speed and a bit more trajectory with a lighter shaft in a club that is typically more difficult to hit.

This is not the first set that someone has written about or even requested that was built in this manner. It is not easy to have a set built this way, but some golfers have very specific desires. If you look back at the weights you sent, note the precise weight ascension. This is too consistent to be a mistake. My best guess is that the original user had these shafts installed to their specific specs.

If you prefer to send the shafts into our office, we will be glad to inspect them, but if the weights are as you write, my conclusion will most likely be as above.

We don't know exactly what the original user/fitter intended, but this is a common scenario. With thousands of installations possibilties, this seems most likely.

As always, my best recommendation is to seek out a competent equipment professional in your area who has had proven success, and work with them in finding the the optimal shaft installation for you game.

Best of fortunes, Mark

Did you buy pull outs or new????

Pull outs.

Yep,

I guess that's why they make you buy them from a "shaftologist".

OK, for those of you interested...

I just got a set of NS PRO 950s in stiff delivered, brand new, still in the plastic. They are all dead-on-balls-accurate to 97 grams. Every one of them (35 inches to 39).

Here is the interesting thing... Unlike the 1050s which all bear the same manufacturing date, these were made on all different dates in 2002. However, they were obviously sorted for weight.

Another interesting thing. The 1050s are not 7 or so grams heavier than the 950s as they are supposed to be (except for the 3 iron shaft which is 104). They are an average of about 18 grams per shaft heavier!

What's up with that?

How did your Nippons turn out now that the 95s are constanty weighted?

I see that the 1050s in X-stiff are supposed to come in at about 114g acc to the specs.

How is the ball flight, distance and dispersion?

I had some 1050s in regular and wow were they soft, much more so than the 950s in regular. I would opt for the 1150s or 950s as they get rave reviews. Not too much postive feedback on the 1050s from what I see.

Hey Richmond, holy thread revival! This one was from 2003 LOL.

Since its been revived, might as well add something constructive.

I had a set of 1050s ordering to go with a brand new set of miura irons, and the specs we
