man, i absolutely give up on wick based systems. try as i might, ever since i've upgraded from ego twists and moved on to more advanced vv devices or even kicked mods, i can't get them to work. not even rebuilds (which i have admittedly almost no experience with making them or using them-maybe tried them twice, three times max). i loved the vivi nova minis on my ego twist, but now, all i taste is burned wick on everything with a wick. even at low settings, i can't get no satisfaction. bottom coil wicks, ce3's...burning wick. i am hoping ss mesh will work better when i cross that bridge. but so far, nothing beats a freshly filled and properly primed carto tank with a single coil 2.5-3 ohm carto.
