I got my first carto tank with a two hole carto. I used a 50/50 liquid it didn't wick well, so I tried slotting and that was a disaster. I would rather get prepunched cartos. I found three hole cartos and they're great, but they aren't as common as two hole cartos. I prefer vaping at higher wattages, and it kills my cartos faster than I'd like. I found a couple high resistance cartos but they only come with two holes. I prefer 70/30 anyway, but I found out I can't even tolerate 50/50 liquids (coughing fits) so now I only use 70/30 or 60/40. Does anyone have issues using liquids in that ratio with two hole cartos?
You're kinda like the Yoda of vaping, without the whole backwards speech pattern, and hopefully not so green.
