As you can see, I'm already a fan of the FA despite I haven't even opened any of the bottles yet.
Indeed and you have a nice collection of fruits that you can do a lot with. I'd probably start with one of those Oranges or maybe the Juicy Strawberry and mix up a tester at 2% fruit and 1% Fresh or Vienna Cream. If you have it, Vienna might be the better choice because it adds a little sweetness that you don't really get with Fresh Cream, or at least I don't. I find Bilberry, Fuji, Grapefruit and Raspberry quite strong so I usually start them lower when building a mix. I love FA Pineapple but I have to be careful with it because it can give me indigestion, just like the real thing!
As you know, FA flavors are fairly strong so I usually start around 1-2% with a primary flavor unless I know otherwise in advance. While it isn't usually a primary flavor, FA Honey for example, is extremely potent so starting at even 2% would probably hurt me, lol.
Dive in anytime you're ready, the waters fine!
