John,
I think you are addressing two different things here: polarizers and UV
filters.
I haven't seen comments about B+W, but some companies do make two versions
of filters. Some filters (more expensive) are made thinner so as not to
interfere with wide angle lenses. That's one nice thing about OM filters,
notice how thin they are!
Some Tiffen filters for example are quite thick (the metal mount), some
Hoya's are too, but some special Hoya's are quite thin. My guess is that
B+W has used some of the same manufacturing techniques. Maybe they're just
following the lead of Olympus.
Use of a UV or Skylight is rather a personal matter, there are camps both
ways.

I wonder if someone could comment on something I heard yesterday in one of
our mainline camera stores about UV filters. The store person mentioned
that
B+W makes two types of polarizing filters; one with the distance between
the
two rotating filter pieces the same as that of other manufacturers, and
another where the distance between the two rotating filter pieces is much
smaller. The store person opined that the latter type of polarizing filter
could be used with wide and very angle lenses without any negative
consequences. My experience with UV filters is limited having only
acquired
an SLR earlier this year. As a long time rangefinder camera user I never
used a UV filter so have no experience in that field.
