David I don't know of any group working on wicking. We really don't see much of it anymore and if excessive wicking is present there is usually more problems than wicking. My only concern regarding wicking is I think it should not be 3 mils for a max limit, but 2 mils (or whatever internal annular ring minimum limit is established). That way the wicking would not extend past the internal annular rings.
