More specifically in a Titleist 905T AND 905S. What is the biggest difference in each shaft (feel, launch angle, etc...) and what will it do to each club.

I was going to go with the Callaway 454, but the Titty is just too much to pass up.

blue>. best i feel for a quick tempo swinger.. a little firmer feel than the nv-65 - it has a very silky feel to it.. ball flight for both real close.. nothing too high-- mid ball and good distance with both.. the blue just seems to play best with quicker hands players.. form what i have noticed and hit..

Blue is more consistent for me -easy to fade, tough to draw; takes the left side out of play. NV may be longer, but I don't know where it is going. Both have about the same launch angle. NV feels livelier, Blue is firmer.
