I don't remember always having this problem, but lately I've noticed that my cartomizer is having trouble wicking with the liquid I use, 65%VG/35%PG. I was wondering if there was a cartomizer with prepunched holes larger than the typical 1mm size. I have to use a drill bit to bore out the ones I have gotten already. A carto punch bends the metal too much for two of the tanks I use that have a really tight fit for them. Most atomizers I've tried don't work, and I actually prefer cartomizers anyways. Is there a cartomizer with a different wick material? or are there ones where the pre-punched holes are larger?
