Think I finally figured out...

why madvapes' pre-punched cartos have such small holes! Maybe it's because the liquids they sell work perfectly in them. I got a sample pack of liquid just to try them out, and sure enough, the first liquid I filled the tank with works great with that little bitty hole. Of course, it sucks that I've already cut slots in all of my other tank cartos. Oh well, maybe I'll get lucky and the madvapes liquids won't flood out with the slotted cartos.

I've been aching to try a tank system out but the reviews about the small holes on the madvapes cartos have been dissuading to say the least. Hearing this though makes me want to give it a shot. I have two bottles from them that came with a 510 box kit I ordered so I could give those a try. I don't own a dremel nor do I know how to use one so I just don't want to be SOL when I get it.
