I've harvested 2HA yeast and it did ok, but then I grew a large starter from it over several steps. Next time I'll try the Oberon. I really should stop by next time I'm in Kzoo and take a tour and ask questions.
Funny thing is that after I harvested the yeast, I went ahead and used it, and fermented too warm. This was just before I finally forced myself to follow good temp control practices.
I KNOW my next 2HA attempt will be killer!! (that's what I always say...)
