I seem to remember 2124 being something like 48-54° but then something like 72-76° or some crazy thing. I never used it warmer but it's interesting to know you could use it that way.
When I first used it as an ale yeast (fermented around 68°); I expected an estery mess, but instead I got a good, clean IPA. Color me surprised, but pleasantly so.
It was an experiment, sure, but it was nice to know that I could use 34/70 for ales, especially in a pinch if, for some reason my on-deck ale yeast was no good (contaminated, too old, etc.).
