Welcome!! Personally, I don't see why you don't just get some XL or reg sized empty cartomizers from SI...they have very good ones. I believe Kanger makes them...probably among the best in the biz. I never have had much luck with wick type
tanks, and believe me, after over a year, I've tried a MESS of them. Don't use them anymore. I get just as much if not more flavor and TH from using a good cartomizer in a cartotank, or even just on it's own (on something like the Volt, especially).
I know a lot of people are going on about those clearo type
tanks, but honestly they might be okay for some people, but they really are fiddly and hassle/leak/issue prone. I just want to fill and
vape. Period. KISS.
