Wood swelling with harmonicas

[harmonica]

To whom to may concern:

I am wondering what varieties of wood resist swelling.

I make harmonica combs and any distortion from moisture will cause swelling and eventually air leaks. I understand that bagpipes use African Blackwood. Are there other woods with this type of characteristic?
