I would tend to think as a general rule that the least amount of weight possible would serve for the needle-cut discs. I can't imagine anything more than 6 or 7 grams being healthy for the records, but I'm basing that on how the thought of a diamond stylus with a half pound of pressure plowing through shellac and spitting dust aside makes me cringe, not any sort of technical knowledge. I'm curious, can you set the counterweight where the tonearm will float in the air like many modern turntable tonearms?
Too bad Thom wouldn't license his patent for the DDs' surface (I'm assuming), which could obviously withstand the punishment with ease... Columbia's Viva-Tonals got close and I think they're pretty much the best sounding 78's out there.
