This thread is interesting, It is a progression that arrives at squonking that for me, kinda went like this. Subohm tank, leaks and poor flavor, RBA deck in subohm tank, better flavor, still ocassionally leaks. RDTA, Flavor good, Leaks when not level, RTA flavor good, doesn't leak, goes through juice quickly, RDA flavor nirvana, doesn't leak (easily), hate constantly having to drip...Pulse Mech BF, Liked it but it was always wet with juice somewhere, Relegated to 2nd fiddle to my RTA's. Topside Dual...now we are talking...10 mil capacity that is not constantly wet, All day vaping on an RDA without having to Drip. Now the RTA's relegated to 2nd fiddle. I think it is largely setup dependent. If it's good as a dripper, It will likely be good as a BF RDA. Preferrably top or side airflow. The bottom line is, I found what I preferred to Vape, and then thought about the most efficient means to keep it juiced up...Hello squonking!
