Congrats on blooming a roth, it's always a pleasure to see one in flower!
Since there's already an interesting discussion going on here, I figured I would throw in my 2 cents on something that's been mulling around in my mind. I'm interested to hear what people think about it. Mainly, when did we start conflating "wild" and "old-school" roths with "poorer flower quality by judging standards". That is to say 'Rex' and 'Mont Millais' are wild collected specimens, and they have incredible color and broad segments. To illustrate, here is a recent photo from TON of one of their flowerings of 'Mont Millais':

The form, balance, color, and presentation of Mont Millais are still exceptional, even when compared with more recent line-bred roths, in my opinion. Even "old style" roths can have broad segments and bold striping. Here is a picture from the June 1936 issue of Orchids Magazine, featuring a roth (almost certainly wild-collected) bloomed by the orchid firm of Lager & Hurrell (Summit, New Jersey), that won first prize at the International Flower Show in New York:

To me, this "older style" (1936) "wild" roth is an almost dead-ringer to some of the roths that came out of the early generation of Orchid Zone crosses, and it's still of above-average quality by today's standard. Just to be clear, I'm not trying to put anyone down, and I'm so glad there are growers who appreciate and preserve different styles and breeding lines of rothschildianum. But I have just been thinking that the terms "wild type" and "old school" have morphed somewhat into euphemisms for roths that don't meet current breeding standards (which are entirely artificial). Perhaps this is a result of the Charles E x Borneo cross, which was one of the earliest commercially successful crosses, and tended to give progeny plants that don't meet today's judging standard. I guess my point is that "wild-type" and "old-school" roths can still be big, bold and beautiful, and that we're still in the relatively early days of line-breeding for this species. Even the latest, cutting-edge Paph Paradise crosses retain the fundamental aesthetics of wild plants, even ones photographed back in the 1930s!
