Yep, strictly MTl, and there's a reason the 'l' is lower case. For me, it's actually more mouth-to-throat. 13 mg/ml, from mechanical squonkers, about 5 ml / day.
Pretty much the same here, and generally exhale through the nostrils.
Toppers are either EHPro KFL2s or Coppervape Skylines. (I think it's 8 to 4 atm

) All different homebrews, all 18 mg/ml. Maybe, between the dozen, 4 - 5 mls per day. Coils start at 1.5 Ω, 8.5 watts.
Assorted regulated boxes, some Cloupor Minis, Pico 75s, a Smoant Battlestar, IPV D3, Wismec Pressa 75TC, Innokin Proton,

and I probably left somebody out...
