The Fujikura Motore Speeder VC6.2 Tour Spec is exactly what it says it is, a tour shaft geared for distance. The Speeder VC6.2 will give you the lowest launch of the entire Speeder series, along with the most roll. If what you're looking for is a piercing flight in a moderately weighted shaft, the Motore Speeder VC6.2 is what you need.
Kevlar Triax is designed to reduce ovalling on the Motore Speeder VC6.2. 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.
