The Nippon 1150 is a nice shaft, it is one of the recommendations for my DNA so I have tested it several times.
The Nippon 1150 is quite different shaft to the Nippon 950 and is distinct in the Nippon NS Pro line. It has a stronger butt and tip section than the Nippon 950. In DNA terms it fits a player with a mid tempo, mid to mid release swing, where the Nippon 950 is the perfect match for the smooth tempo player with an early release.
It should launch a little lower and spin just a little less than the Nippon 950. It has a very similar bend profile to the DYNAMIC Gold XP which is stock with some other OEM's.
Funny you mentioned the DNA fittings. Mine were:
DG XP S300s
Nippon 950 stiffs
KBS Tour stiff softstepped
I had MP64s with the 950s and hit them too high and lost yardarge. Loved the feel though. So I took a gamble on 1150s even thought they weren't in the DNA fitting.
