In comparing the Rapport core Blue S flex 80 (actual weight 85 grams) to the NV 85 S (actual weight 88 grams), the Rapport has a lightly softer profile than the NV. I looking at the butt, mid and tip sections, the overall profile is not as firm in the Rapport. Both are Mid trajectory and that is accurate based on our testing, even with the Rapport not being as firm throughout the length of the shaft. The Rapport fall on the average line of all S flex Graphite iron shafts. In other words, of all the S flex shafts we have measured, it is not on the soft side of the S or the firm side of the S flex range. It is right in the middle, average. The Aldila falls on the firmer side of the average, still within the range of all S flexes, but stiffer than average.
