A blueberry I highly recommend is Flavor West Blueberry mixed with Flavour Art Bilberry.
I tend to go for a 8% blueberry with 1% bilberry works really good together.
Couldn't agree more.Yup FW is a great blueberry, I normally use it at 5% with 2% TFA blueberry xtra and 0.5 FA Bilberry (any more and it starts to take over for me). In saying that blueberries are hard one to nail down so always tweaking...
