When to do it - do it now

[Marcel Carey]

OK, I'll give this a try. My understanding is that studio keys being smaller
in height (less wood) don't move as much as thicker keys. I personnally
think that it is only the thickness of the keys that make for all that
seasonnal changes. And then I might also be wrong, but this is the only
logical cause that I could think of.
