Fran, have you tried the Natures Flavors caramel? If not, I can send a bit up. It's pretty decent.
My all-day, every-day, is vanilla tobacco:
12% perfumersapprentice tobacco Blend
8% natures flavors organic coffee flavoring Vanilla
I picked up a bunch of GoodProphets 36 mg/ml, it's been testing fine and their sale prices are sweet, and also use MFS 60 mg/ml. (100 mg/ml is slightly better price, but I find 60 simpler to work with.)
This is my version of Caramel, Coconut Cookie:
Total 20% flavor (Flavor Art flavorings is what I use for this)
37.5% Caramel
37.5% Coconut
12.5% White Chocolate
12.5% Cookie
