Thanks for the information! I appreciate it.
It looks like it's more popular than my first search results showed (it's all in the spelling, it seems). Lots of vendors sell it, apparently.
I like acidic tomatoes. Well, I've found a couple kinds that I didn't prefer so much (like an extremely sour Lemon Boy F2 I grew last year, which although it tasted fine, it seemed to be chelating my teeth considerably, unlike the F1. And, a red cherry tomato that tasted like certain kinds of commercial canned tomatoes taste; my youngest sibling loved it on pizza, but I preferred it in small quantities, and not on pizza; the acid had kind of a burnt taste to it, I thought; the plant was productive, for sure—I don't know the variety).
