The Fujikura Motore Speeder VC6.0 is built for the average golfer that's looking to get their ball flight up a bit, and increase carry. The VC6.0 has a mid/high launch and mid/high spin, with a mid tip stiffness. The Motore Speeder VC6.0 has a middle of the range torque at 3.5. It's not specifically designed to increase your roll, but it will increase your carry.
Kevlar Triax is designed to reduce ovalling on the Motore Speeder VC6.0. 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.
