I did mention using my tanks, mostly, for out and about. But RDAs are my primary. And with a little research, you can find one that doesn't leak (Hastur *knocks on wood*). And I didn't say RDAs were "better" or superior, just what I prefer.The OP wanted to know about RDAs. You said " But I agree with everyone else, with the new sub ohm tanks, you won't want to use your RDA as a primary as it can get a bit tedious with the rebuilding and easy leakage" With the exception of a sarcastic post, no one said any such thing, in this thread. I'm not picking a fight, but stay on topic please...thank you.
