With the right RDA, build and etc., you will be TOTALLY fine. I promise. You should have seen some of the clouds my kid made with my build, it was redonkulous.
Remember, with mechs, it's your build, and your battery I actually use the Panzer RDA but with one coil. I don't like small bore drip tips etc. If I added a coil to lower the resistance and went nuts, I'm pretty sure I could produce some crazy clouds, actually, even probably safely with my battery I have in there at say around 0.5.
You'll be fine. It's the battery you go with, how you vape it, etc. I don't take the longest draws but even with my build I'm usually far cloudier than usual. Etc.
Don't sweat it, I kind of threw a bit of MTL out of the window with my mech and I get pretty cloudy even so, with my puny build (but I have mass in my build too, so that adds to things).
Don't worry,
Anna
