Yes, I had them in my set before installing Nippon Modus 3 130 Stiff- amazing how much the Modus "feels" lighter however they are only 1 gram less weight. The balance point on the Modus is closer to the shaft butt. However, I do feel the much softer tip in the Modus. I'll be looking for some heads for the NSPB's, but with a lower center gravity to get the ball flighted quicker.
