I have taken the old uniglide freehub off the 600 hub. As far as I can see there hasn't been any major changes in the design of the freehubs and there attachment to the body of the hub. Therefore the only compatibility issue may be with the fit if the old cones into the new freehub. Anyone have any experience with this?

I am going to stick with 7 speed as the frame is bonded aluminum and I don't want to risk spreading it. Am I loosing all the advantages of the 600 hub by coupling it with a cheap freehub though? I was looking at this guy;

As it is one of the few 7 speed freehubs still around. Anyone have a better alternative? I don't want to spend the same amount as a new hub either though.
