I have a couple of his Blueberry crosses but haven’t grown them yet. Blueberry Cream uses Knik Goose Bay Blueberry and Vintage Blueberry (plus Starfighter!). I also have the Fast Vintage Blueberry, supposedly done in 56 days of flower.
If you’re looking for Blueberry, I’m super pleased with the Pure Blueberry (Blueberry Muffin Edition) from Jordan Of The Islands. I’ve kept two phenos around. The frostiest doesn’t yield as well, while the bigger one produces but isn’t quite as potent. They’re both purple, delicious, and BIG on the berry aroma. I need to grow them side by side again and narrow it down to one keeper…
Edit to add:
Mmmmmm… frosty JOTI Blueberry!
