Barney's G13 Haze still good and what's a reasonable yield from Dr. Grinspoon

I'm seriously thinking of trying these strains even though I was completely unimpressed with the Barney's strains I grew a few years ago and the general negative opinion of his stock you read about on the web. G13 haze used to get uniformly great reviews but I've seen some reviews recently that say there's more variation now in the seeds such that you have to look for a good example of the strain. Since I'm not interested in pheno hunting through Barney's seeds I wanted to know if anyone has grown or sampled the strain recently and whether it's still a winner. Also, I'm thinking of growing Dr. Grinspoon even with its long flowering time but what about the yield? It's described as low, but what does that mean in terms of weight. Grown in 3 gallons of soil would you expect yield to be less than an ounce, between 1 and 2 ounces, or what? I'd be ok with growing her if I could get 1.5 to 2 ozs or so.

Thanks for your help.
