I'd love to see a list of flavors with the recommended brands for each. I started doing a list like that some time ago but gave up, since it got too labor-some and complicated. You'd really also need subcategories, such as:
Raspberry (natural): INW Raspberry
Raspberry (candy): FLV Raspberry, TPA Raspberry Sweet
Then I figured it'd be even better if I listed base recipes for single flavors, such as:
Blueberry: TPA Blueberry Wild 7%, FA Bilberry 1%
Orange: FA Orange 3%, FA Mandarin 1%
Then I gave up.
