I'd like to know. So far, i have three in my Avoid column: GreenHouse, Barneys and Nirvana. I'm not saying no good ever comes of them, but I've read about (and with Nirvana, experienced) serious inconsistency and a prevalence of lousy phenos. I've also heard that Dutch Passion is selling bunk.
The breeder I knew&loved was Bros Grimm. They are no more. I'm still looking for someone as good. cn
