Try Imperial G03 "Dieter" for the yeast. IIRC it's a Kolsch yeast, reportedly the PJ Fruh strain. It supposedly drops very clean without fining but doesn't take forever to do it like WLP-029, which is also purportedly PJ Fruh from Koln. I've got some of it in a Shaken Not Stirred propagation and am anxious to try it. The pouch was a few months past its prime, but seems to be coming around OK. Not sure what to do with it, but "Cof3C" seems like a logical choice as soon as the days warm up a bit. "Sposed to be in the low 20s F next week, so it might be a while. Brrr.
