Of the "cold tolerant" trial last year, Jagodka was the earliest to completely ripen all fruit on the plant and make a decent crop of tomatoes. I had Boney-M which ripened the earliest fruit, but it only made 3 or 4 tomatoes and then died. There were a few others that were exceptional in one way or another, but not-so-surprisingly, true cold tolerance was lacking and what was present was at best weak and unreliable.
