I just bought a D3 from my local shop (like to buy locally), but I'm thinking a lighter shaft works better for me. Can I order directly, or purchase from my dealer, a D2 shaft that's lighter, say 50 g. +/-? Will it work with the D3 head? The D3 shaft is 65 g, If I recall, and I really feel a lighter shaft is better for my swing speed (tops out at just 90+.) Still want R flex, though.
