I cam considering getting an EGO to be able to use Low Resistance cartomizers. I have heard the vaping experience on LR cartos is better, but that a 510 battery doesn't support them. Is there such a thing as a mega carto that is low resistance, fits the ego, and you can just drip into the carto to fill by removing a soft cap or attaching a drip tip. There is no way I will ever deal with syringes to refill these things so the refill part is imporant, but I also want to be able to hold extra liquid in my carto as well.
