i personaly dont like dual coils or boge or any "standard" carto i do like ce2's however the standard cartos in both of my tanks went about a week without that polyfill taste that i just cant stand and the ce2's i used were rev2 and rev3 clearos.. witch if they didnt crack they worked great but they do all eventually crack sadly havent tryed the new rev4 clearos because of that. and most of the ce2 tanks are sold out these days and dual coil tanks are in high demand everywhere. so im probably ganna end up modding a dual coil tank for a ce2 at some point lol.. now it may also be im outvapeing the dualcoils in the tanks and they get too dry and burn the poly. but ive tryed everything 2 holes 1 hole 1 slot 2 slots holes so big the tank floods and juice gets everywhere. and they all eventualyl get that flavor so i think its just me and cartos dont mix.
