Thanks, I figured that was the case because .5 at 10 watts would be so low. Funny you mentioned the mvp2 and vamo 5 as those are two of my main mods and I hoped I could use the Subtank with them, which I guess I could using the 1.2 coils or the rba part built higher.
Right now I have the stock 1.2 ohm coil in it. I decided to try both stock coils first, because I plan on ordering a pack to keep for when I'm on a trip and don't want to rebuild. I wasn't sure which I would prefer, so I tried them both. I think I will buy the 1.2 ohm ones, because they will fire on any regulated mod, and they are very nice. (I have an MVP 2.0 and a Vamo 5 as well as the E-Mech, so the lower ohm ones won't fire on two of my mods).
Good vaping to you my friend! 



Hubby doesn't understand that need though.
