excuse my ignorance for this question .. but i am new to this and i did google it and i'm still a little confused. I got the impression that a cartomizer is an atomizer with poly-fill in it that holds juice and that an atomizer has no poly-fill in it. if that's correct . .then if i bought an atomizer to use with my vapage vmod 2.0 .. then what would be on the end of that? would it be just a drip tip or would it be some kind of cartridge with poly-fill in it and then a drip tip? the reason i'm asking is cuz my vmod 2.0 came with a 2.2 ohm cartomizer and i was told to shop for an 1.5 ohm atty for better vapor .. but when i look around online .. i see them but do they have poly-fill in them to hold juice or what? or should i be looking for a 1.5 ohm cartomizer .. not atomizer? .. could someone clear this up for me? thanks
