DJ's is very nice. I have one pheno that I got from an old grower in cali (original bb, not "true blueberry"). Outside she is done by Sep. 25th with a very good yield proportionate to plant size. She does not smell like blueberries, more of a caramelized muffin type smell with a mixed effect. Inside I'll find out in 2 weeks... Not the most potent in my garden, but I'll never get rid of her.
Dutch Passions version is likely to give you some trannies. The majority of written word on their version has complaints.
I don't know anything of Sag's version, but they are an older, reputable breeder from what I have read.
Another breeder that works with an old "Oregon Blueberry" is Dynasty. You might want to check him out. His varieties will have actual berry smells: Blue Heron, Mt Hood Huckleberry, Blue Magoo BX. You can tell I'm a fan of this family of plants. His gear $50/pack compared to DJ's $140ish. DJ's gear is tried and true but I don't like paying that much. I've got the magoo cut and I'm throwing out a few Mt Hood Huckleberry seed plants this year.
