Loving my new Provari mini with rebuilt protank/protank2 heads using cotton. Just wish they didnt gunk up so fast.
Im tempted to pull the trigger on a kayfun lite. Ive just spent to much money on various things this month.
have you tried an evod head with a SS wick in the protank?
it's freaking amazing. flavor of a genny, yet pocket friendly.
just torch the crap out of the mesh before you roll it, and again once it's rolled (hold it sideways in needle nose) and you won't ever short it.
i have an evod head and a protank head both with SS - each have run through 4 or 5 coils ... so they are like 2 months old. every couple of weeks, i just pulled them apart, quick torch to clean, re-wrap w 32g (4 for 1.8Ω, 5 for 2.2Ω

and reinstall.
currently i have 2mm eko in both of them, just to try it out.
i also have a 3mm eko in my dud, 2.4Ω 30g micro ... not working so great. when this tank is dry i'm ripping it out and building something different.
the RSST has a 2mm 400ss mesh wick sleeved with 2mm eko, free wrapped 32g 2.7Ω ... and it just freaking rocks. been going through 4ml a day in it ...
i have a short piece of sleeved ss wick left over from where i trimmed the rsst wick ... that might make it's way into my RDA. it's too fat to use in a protank head ... and the eko is unravelling a little on the end with no SS in it. i think a vertical coil like i have now, with the frayed end on the atty deck ... i will probably have to plug the air hole on the deck though.
and a quick pic of the dual coil fog machine. i made up some 1mg 10/90 dk tab for this ... 12mg gave me a headache after 2 tokes ...
