okay i fill the dual coil carto let it sit ten minute to soak,then insert it in the tank fill the tank with 70pg/30vg,real good and tasty for 8 vapes,then it gets dry,so i take off my drip it and top off the carto,good for 6-8 vapes then have to top off the carto again,what the hell,now iam thinking about that lil pin hole that feeds the juice,maybe i should be gentle and drill the hole a lil bit bigger....anyone try this?? I purchased 5 extra cartos with the tank so i need to figure this out somehow.....i have the tank on the lavatube vaping between 4-4.5
