Thx for the advice Pete, especially as I read my post and it's confusing (I like the tanks, then...I don't like the tanks, they don't have any flavor). I've burned through atleast 1/2 the tank, just inhaling/exhaling, trying to break it in, starting to taste a smidgett of vanilla, but not much. It was way over with vanilla (my fault, shouldn't of had them add vanilla) with the Go-carts. I'll burn through this tank and report back.
