Yeah, I guess it's not fair to call it "equivalent" TY media, but the 8x +R TY media burns at higher than its rated speed on my NEC 3500. If they cost the same, I'd never buy any of the Ritek media, even if it's officially rated at 16x (unless a lot of people and a lot of testing shows that r04 is as reliable as TY at the same price or less.)
Good point about the Ricoh and MCC options, the made in Singapore MCC spools that I get are a tiny notch below TY media on PI/PIF tests, but theyre reliably good, so I get that in addition to TY media.
Ricoh media seems pretty rare, where would I get some in the US that burns as reliably as MCC or TY (12x or 16x actual burns on a NEC 3500?) Are inkjet printable Ricoh discs available?
