I just bought black cigar, french pipe, cherry, caramel and island tobacco super concentrates from Vapingzone. My first question is if you have used these tobacco flavors, or any tobacco flavor, what % PG/VG tastes the best for you? Second, Vapingzone recommends using 2.5% flavoring. If I were to add another super concentrated flavor to the tobacco, would you suggest using 2.5% of each flavor or 2.5% flavor total?
