I have found just the opposite to be the case. I used to fiddle around with all of the various cart mods, and then I got my BB from altsmoke. Since then, I haven't touched a cart and just strictly direct drip on the atty(510 atty.) Two to three drops and I am good to go for at least 4-6 drags, then the taste starts to change and I know it is time to add a few more drops.
I also keep the heat of the 510 atty from burning my lips by using the silicone cap that comes on a kr808 cartomizer that I cut a hole in. It fits snuggly over the atty and has a hole big enough to drip through. IMO it is the only way to truly enjoy vaping.
