Thank you both for the input. I didn't know about the Wake. Looks like it's for direct lung vapers while I do MTL. Since kicking nicotine really mouth to nose and not even get my lungs involved.
I've never had a drop in or screw in coil short out but in a 35-year career in audio electronics I've seen a handful of qualified technicians make impedance errors and create minor disasters. One lost a good deal of his hair. The blue flames can be pretty though...
I'd never use a mechanical with any kind of coils. Just too dangerous.
