Alan, Absolutely no arguments with your position. I've used collodian/ether combinations for many years - as well as collodian acetone. My experience is that acetone doesn't "carry" as well in dense hammers, and that the mixture seems to sometimes cloud. (OK, so, it's a personal issue...) My main concern, however, with the use of ether is flammability. The flash (read "ignition") point for ether is only 140 degrees F, with a relatively small ppm (parts per million) ratio. Normal incandescent lights are hotter than that. As a further note, I very seldom use collodian at all on "soft" (read NY S&S, or Ronson) hammers, preferring "heavy" (automotive) lacquer and lacquer thinner. (Do it once. Do it right. Leave it alone.) However, collodian _is_ my hardener of choice (when any hardener is necessary, to begin with) for hard or "hot" pressed hammers. I simply prefer the sound. To _my_ ear, it is easier to develop the kind of well centered, carrying sound, with the widest possible dynamic range, using these methods. As you read this, bear in mind that I do not like what has come to be contemporary piano tone. I find it shallow, lacking in well-developed color, sometimes decent pianissimos going directly to often splatty fortissimos (with very little in between), et cetera ad nauseum. (Most artists do not like it either, but they _do_ like to be nominally as loud as the instruments {orchestras, whatever} around them.) By-the-bye, outside of the pharmautical industry, the widest use of collodian is in stage make up. Just thought you'd like to know... Best to all.
