So rainbow sherbet sounded pretty good for this warm day. I mixed one up with FA flavorings, and I'm liking this combination a lot.
"Maybe It's a Rainbow"
2% Vienna Cream
0.75% Pineapple
0.5% Custard
0.5% Mandarin
0.25% Lime Cold Pressed
0.25% FA Raspberry
Lime and Raspberry are stronger than Mandarin, and Pineapple is the least potent, so this is a fairly balanced mix of those 4 flavors when mixed like this. Custard adds sweet/cream and some citrus zip. Vienna is working as a sweet, ice cream type background. I like it well enough to vape a tank or two (I'm not a huge fan of fruit flavors). Double this strength would be too much for most people; as-is might be too light. It's right for me.
As I said earlier, I've never tried Sherb, but this is definitely rainbow-sherbet-ish. Maybe it can give you some ideas. With luck, someone who has tried Sherb will have some comments for you.
