The Fujikura Motore Speeder VC7.2 will launch lower than any other of the Motore Speeder VC series except for the Tour Specs. Lots of roll, and more distance is what you will expect from the change to this shaft.
Kevlar Triax is designed to reduce ovalling on the Motore Speeder VC7.2. What that means is throughout the swing and at contact the shaft will maintain it's circular shape. What this actually does increase stability of the head during impact.
