I think the only flames you will get is this buisness about the aging of wood.
We have a few folks here that adamantly deny that the acoustics of a peice of
wood can possibly be influenced by its age. This despite the fact that the
incidents of subjective observation to the contrary are so enormously numerous
that it would seem impossible for the reasonable mind to avoid being  forced to
wonder whether or not the quanitfiable factors relative to soundboard acoustics
are somewhat lacking. In anycase it seems to me that the validity of the "old
wood" theory remains very much an open question.

As for recrowning... seems like there are several on the list that espouse this
proceedure.
