I've read that most people flavor their mixes with between 10-20% flavoring. I received an order of flavors and am mixing up 3ml bottles of each individual flavor just to see what each flavor tastes like before I jump into blending flavors. My question is, if the goal is to get a true test of what a particular flavor tastes like when mixed with nic, pg/vg, what is a good percentage of flavoring to use for the tests? Should I start on the low end and hope its strong enough to get a good idea of what the flavor tastes like, or start more on the high end and hope its not so strong that it takes away from the true flavor?
