One key advantage of an isolator manifold system that (I think) no one
has mentioned yet is their suitability for those of us who frequently
use full face masks in extremely cold water.  With independent doubles,
a reg switch is necessitated just to be able to follow proper gas
management procedures.  (unless the rules are different for
independents, I wouldn't know...).  With an iso manifold, if there are
no failures, I keep the mask on for the duration of the bottom gas
profile.  Granted, a mask/reg switch is no big deal (if it is, you
really shouldn't be diving), but if I can keep my face warm and be
safer at the same time, why not?

Then there are the multiple safety advantages of an iso manifold which
have already been stated numerous times on this list.
