I'm relatively new at this (just going into my 4th season), so I am
definitely interested in hearing from others on this topic.
I use an inner cover & telescoping cover on each of my 10 hives.
It seems to work well for me, providing the right balance of
ventilation and insulation. I rarely move my hives, however, so
the advantage of "migratory covers" (i.e. a sheet of plywood as
described by Mr. Lord) and close packing of hives is not so
important to me. Also, the winters in the Boston area are a
bit more severe than in North Carolina, so winter insulation is
much more important to me. The majority of hobby beekeepers
in my area use the same inner/telescoping cover combination
that I do, but most of the commercial operators use the
"migratory cover" due to the advantages of close packing, and
reduced equipment cost per hive.
