I got three new flavorings in from TFA yesterday: Ruby Red Grapefruit, Coumarin Pipe tobacco and Whiskey (which I'm hoping is something like Scotch). Any suggestions of what percentages to start these at (and go from there)? I like my flavors really strong. For example, I mix my Cinnamon Red Hot at 15%. I'm thinking of starting the tobacco at 10%, the whiskey at 15% and the grapefruit at 20%. Does this sound reasonable?
