The IKV visions or the clear dual/single coil versions?
Isaac makes the best dual-coil clear cartos I've ever used.
The IVK Visions
tank cartridges work pretty well, also. TBH, I drip a lot, but I will use the dual-coil clearo's quite often.
My impressions of the visions are that they do perform well, and the ego version allows you to either drip or fill the
tank, so there's that- it also fits perfectly on an ego or ego-threaded device like the KGO; cleans up the look. Personally I'd like to see one of the
tank cartomizers with an io6 or cannon guts put inside. That there, would be the perfect vape with absolutely no mess or muss.
