[Avodah] [Areivim] [w]hats the norm?

relative merits of Davening with a hat vs. Davening without a minyan):

It actually is a Machlokes Rishonim - the BY (OC 8:2.2 - MY edition) says
that it's Derech Tznuin based on various Gemaros, and the Darkei Moshe there
argues and says that one is not obligated to if one is not wearing Tzitzis.
(IOW, BY says that one should have two headcoverings, and DM says that one
doesn't _have_ to wear even one.) (However, see Darkei Moshe 2:2 who talks
about how important it is to cover one's head - presumably talking about a
single covering.)
