Notice any marks on the neck caused by the round wound strings?
My spectorcore fretless has a rosewood fingerboard. I've never seen a rosewood not get lines ground into it with round wounds. Mine does. You can always wait until the wear is too extreme and get it sanded smooth. I've toyed with a thin CA or epoxy coating to reduce the wear. Not the thick glassy finishes, just a thin coat that should at least reduce the wear enough the my kids can worry about it once I'm gone.

If I just wait for my NS-2 that'll go away. (I hope)
