Nippon N.S.Pro Modus 105 Review

Nippon N.S.Pro Modus3 Tour 105

The N.S Pro Modus3 Tour105 was released to the US public in August 2015. I had seen a set of these earlier in the year, labeled Prototype ST. The Modus3 Tour 105 is the same shaft that has been available on tour for several months. The word Prototype has been replaced with Modus3. I have been told it was put in play by a number of players. Lighter weight iron shafts are gaining broader acceptance in the tour community. In a slightly different form, this shaft has been with us for quite some time. The Modus3 Tour 105 is very similar to one of my long time favorite shafts, the N.S.Pro 1050. Lets look at the charts and numbers:

This is a discussion about Nippon Golf Shaft shot at the 2016 PGA Merchandise show. Be warned, it is a technical discussion between technical fitters.

The English Nippon Shaft site has been significantly updated recently. The update shows and explains the EI profiles of the Modus products. The section of that site that discusses EI profiles is excerpted below.  When one of my fitting associates happened on it, I got a call telling me they copied my graphics. I had to explain, sorry, in fact, they were first, I copied them. Nippon and the other major shaft companies have designed and manufactured shafts with 3 point EI software for decades. It is only now, that the golfer and club makers are developing literacy in the language  of the shaft engineer.
NipponWebGraphicsNippon is one of the few shaft companies that has for many years explained and defined their products to club fitters with EI graphics. The other is Mitsubishi Rayon. The 2015 Fujikura shaft product brochure does the same. This is the language by which one can under the subtle nuances of today’s shaft choices.

    Can you tell me how the modus 105 would compare with the 1150 tours or are they completely different?

    • They are quite different. The 1150 has a very stiff butt. However, when I opened the software, quite by chance, the Projext PXi 120 5.5 was on the screen . When I pulled up the Modus3 tour 105 S I found a perfect match. That is interesting. The Modus a a few grams lighter, but the shafts are much the same in all aspects, EI, GJ and hoop stiffness. You will have a hard time telling them apart.

    Can you please compare Modus 105 to KBS Tour each in Stiff? Thanks.

    Any chance you can explain the influence of added length of the 105? Let’s say 1.5″ over your “standard” length. Is the flex going to drop dramatically? Is there a close to one to one with hard stepping and adding X amount of length to keep flex? Say, hard stepping X2 and adding the 1.5″ flex profile difference between straight in std length, head weight being to same.
    Thanks, Todd.

    • Wow, 1.5 long on a light weight relatively soft 105 gram shaft. Not certain I would do that without building a test club before I did a set. You can always put an extender in a fitting club and see what it feels like.

        Well, they are the ST prototypes. I’m mostly sure it’s the same profile and all as the 105’s? Is that correct from what you’ve seen. They have a XX version that’s supposed to be very very stiff, maybe I should look into getting those.
