The "Stock" shafts are most likely the same as those available for the D2 & D3. Take a look at the Custom Options booklet (select your desired club and scroll down for booklet link). There are quite a few that are not stock, but are available at no additional uncharge. It's always great to do a little research, but work with your fitter to decide on the best head/shaft combo for your swing.

Like Barry said above all the stock shafts are available with that head. All the diamana white, blue, and red. The aldila rogue black and silver. We also just put the Motore Speeder 661 tour spec and 757 tour spec shafts in as stock shafts. There are a few more that we offer. Those are the ones I use most in my fittings. But again like barry said talk to your fitter and go from there. That'd be the best advice.
