For anyone who has recently switched from thanks/clearos to RBA's/RBD's, did you notice much less need to "draw" or "pull" than from the other options? With my Vamo + KFL clone, I can just fire the battery and let it flow into my mouth and then lungs, rather than having to pull on the vapor. The airflow on this clone is *perfect* for me, not too tight and not too airy for when I do pull on it but I find it most enjoyable when I just let it do the work. Maybe I've just been vaping wrong this whole time, lol 
Second question is based on a battery post I saw yesterday. I currently stack 2 350 batteries (Efest IMR) in my Vamo, but they say not to do that in the thread I read but it was mostly focused on Mech Mods I think. Just curious, I don't want to hurt my batteries by stacking them. I'm not really feeling a Mech Mod at this point though I will probably pick up a SemoVar in the near future, for whatever that's worth.
Thanks for any input!
