IMO it couldn't hurt to try a little of the Lotta Latte "One Stop Blend" flavoring with a little bit of the vanilla eliquid that you really like. I'd start with a real small amount though to try for a good ratio of the 2...like 5mL of your Vanilla eliquid + maybe 2-3 drops of the Lotta Latte at first. Give it a good shake, and then test vape a tiny bit to see what you think. If it's not enough of the Lotta Latte, add another drop...shake...test vape. Keep doing that until it's to your liking. Make sure you take good notes on how much you're adding to get it to what you want. That way you can make more of it later in a larger amount if you want to.
In fact, since you're in Florida, too, and I have a good amount of Lotta Latte...if you'll PM me your info (name & addy), I'll just put a very small bottle or vial in the mail to you for free. That way you don't even need to buy 8-9mL of it, nor pay about $3 shipping for it.
