I was just curious if z atty pro and kayfun are rbas that you don't have to drip and get the same vapor production
I'd have to say no for several reasons.
if you want the biggest "clouds", you'll want to vape %100VG juice which is thick. You can use that in a tank system, but it won't wick as fast. So, you could vape, and wait for it to wick back up, which you could just drip and re-vape. The second concern, is you can have multiple coils (four or more) in a dripper, and the most I've seen on a tank system is two. If there were more than two, I'd be concerned about the heat getting to the rest of the juice. So, if you're just going for clouds, I'd have to say no.
HOWEVER, to me, vaping isn't about the clouds, it's about the quality. vaping clouds is more for aesthetic reasons, and to me has little to do with quality of vape. I vape both dual and single coils, and my go to device is a genesis style tank, single coil. It produces a steady amount of vapor, and great flavor. There are other tanks that produce good vapor. My dual coil Aqua is what I use on my mech mod. it gives me some warmth and is virtually leak proof. I use that for my higher VG jucies too, since it has a juice control that can keep up wtih the coils. I am hesitant to go too low on the ohms though, due to the fact that if I heat it up too much, it might affect the un-vaped juice in the tank.
