Has anyone experience using plain strings for the lower resonance strings?

The sets I see (e.g., from ANA) all use wound strings for the lower
resonance strings.

I have problems with the resonance strings that run around my lower
C-string peg - the winding on one has frayed due to contact with the
C-string (which itself is wrapped around the peg, as you'd expect).

It would seem that plain strings would be immune to this fraying problem.

A lesson is to loosen the resonance strings before turning the
C-string peg (not that I do so often - usually the fine tuner suffices).

It doesn't seem possible to position the C-string winding so that the
resonance strings don't contact it.

I suppose another solution might be to put a cap over the C-string peg
(something like a pen cap) so that the C-string winding is covered,
and then run the resonance strings outside the cap. Such a solution
wouldn't be very aesthetic, of course, and could lead to other
problems (rattling, buzzing, misalignment of resonance strings with
the slots in the nut, etc.).
