Nippon N.S.Pro Super Peening

I am in the process of rebuilding the Fit2Score shaft knowledge base with 3 iron and wedge profiles. Nippon sent a box full of review samples including the N.S.Pro Super Peening Orange and Blue. I had briefly looked at the Super Peening Blue wedge shafts in the past. They had been suggested as a wedge addition to my fitting system. Readers have asked several times about these shaft so I was interested in getting a full set of measurements of these samples.

The N.S.Pro Super Peening shafts are no longer shown the the Nippon brochures. I had to find a 2008 catalog to see how Nippon presented the shafts. The descriptions there were brief, and the terms used to describe the shafts Orange = Mid Kick Point and Blue = Butt Kick Point brought me back to a time when I was taught to think about shafts with those terms. We were taught back then that the higher the kick point the lower the shaft would launch. My exploration of EI profiles vastly expanded my understanding of a golf shaft beyond things like kick point and frequency matching. As I looked at the measurement of these two shafts I realized they are good examples to discuss the nature of 3 point EI profiles.
