Philly: you rang?
I've been out of the country, so sorry if I am trying to revive a dead horse, but do you have a general preference for rosewood vs. maple?
Otherwise, all other things being equal, I'd go with the rosewood, mostly because the CBS poly finishes can be very thick. On a maple neck, this can make you can feel like you are playing a piece of plastic. I am not sure how much that really affects tone, especially through an amp, but a lot of people don't like the feel.
Otherwise, most of the advice is dead on, although I would say that a lot of the complaints with late '70's necks are related to the fretwork. Frets take take to get right and CBS often rushed necks though. However, this is relatively easy to fix, even if the neck hasn't been refretted already.
