Hi Geoff,<div>I was mildly surprised that neither our spelling police nor witty folks commented on your "magnate school." Is that a misspelling for "urban high school allowed extra high quality infrastructure & staff hoping to inspire gifted urban students", or "the kind of school George W went to" (Philips Academy, Andover, MA)?

In other words, I'm citing Jim Harvey's "Rule of Six": if six of a certain component set fail, replacing the whole set (or at least acknowledging that the whole set is highly likely to fail at any ol' time) is the proper repair. As Paul noted, cost effectiveness is also a consideration. Light filing to remove the cupping should improve the tone (& if any more felt is loose on the core you'll probably notice it).
