Just to give you my experience of wooden-combed harps....
I have a Marine Band in A which, after reading in a couple of books that it was a good idea to soak (wooden) harps before use, and to shave off protruding bits of comb while soaked, I did just that.
I only cut down the bottom 4 or 5 segments of the comb, since these tended to swell up a lot more, since they are played more. Then I had the problem that the new wood thus revealed was very dry and frictive (?), so I re-varnished the exposed edges.
All well and good, but since then I have hardly used the harp, for several reasons:
1) If the harp is not yet "soaked" (like when you pick it up in the morning) then the leakage around the incomplete comb elements make playing a night- mare.
2) The imperfect varnishing job (my fault, I know) still plays havoc with my lips, as do the uncut comb elements which eventually protrude after playing a while.
3) I bought a few Pro-Harps (black with a full plastic cover over the comb - I don't know if the wooden comb still lurks therein) which are kinder to lips than Johnson's is to a baby's bottom.
The sound from wooden combed harps which are perfectly dry may be slighty different from that from plasticos, but without your lips, you can't play a note (nose-tooting accountants excepted!).
To sum up:
IMHO Burn the suckers!.
