Perhaps I've lost track of what is meant by "two skinny wires". My ownthat
analysis was to calculate at an arbitrary location in space the field
would be produced by a solid wire, and the field that would be producedwhich
instead by a wire whose diameter is the same as that of the hole and
carries current in the opposite direction. The currents for these twoit.
different current distributions are adjusted appropriately so that the
vector sum of the two calculated fields is equal to the field at that
location in space for the actual wire that has a (longitudinal) hole in
Since the sources are the same, the field must be the same, at all
locations in space. No?

My assumption -- now as one has suggested for possibly a different
configuration, is the field inside the wire the same for the two cases?
bc's intuition says yes.
