Shafts similar to Nippon 115’s?

[Bigjim1022]

On a whim I bought a set of Nippon 115s because they were really cheap.  After a few years in PXLZ 6.5, them X100 and then S400s I threw the 115s in a set of irons I have and found I really like them a lot.  
 

I also notice that almost no OEM offers them as a shaft option so I’m curious what plays similar that I ca. order in a new set of irons?  I’ve tried the 120s and don’t like them as much 🤷🏻‍♂️

DG120 would probably be the closest since the Nippon 105-115-125 were all based on a somewhat DG profile.

Why not the DG115 mid?

DG Mid has a stiffer mid section. Modus 115 is a mid bend more similar to

standard DG, but has a little stiffer handle.

I was going mainly on weight. Presumably the person was using X in their irons since they listed using PX 6.5 and X100 in the past. The DG115 X100 is 116g while the Nippon 115X is 119g. The DG120 is 120 in X100, so it would match more closely in weight (and according to above) also bend profile. I had no idea there was that much technical difference to the mid under the hood. I just thought it was a DG with a slight drop in tip rigidity.
