I lived right near Montrose, CO for years. I never once heard of anyone growing this varietal commercially. I have grown it, the flavor is mediocre. It is typical but not exceptional for cold and drought hardiness. It's just a pretty standard apricot. I honestly think the varietal is a bit of a gimmick.
I would go with Goldrich for fruit. It's a superior varietal for Zone 5/6/7.
FWIW, I've had lots of apricots with sweet pits over the years. I don't think it's either as rare or as stable of a trait as books
might seem to suggest.
In Traditional Chinese Medicine, bitter apricot pit is called Xing Ren, and is a commonly used medicinal
herb. It's bitter, and used in medicinal-size quantities. I ate a few with some white chocolate the other night and it's a nice combo.
Traditional Chinese Medicine also does not have any concept of a sweet pit apricot (never seen it mentioned in any TCM nutritional text), so that's a bit of a head scratcher on origins of the 'Chinese' named cultivar and its association with being 'sweet pit'.
Hope that helps-
