I really like the vivi nova's and the new stardust rebuildables, the replaceable heads work great in 1.8, 2.4 and 2.8 ohms. I use a vv lava tube for the vivi 2.5, 2.5ml tank and my ego batt for the stardust and would like to try my hand at re-wicking and coiling etc; The got vape's site always say's their getting in wick and coil packs but never do. So I'm tring to find these in the right AWG wire and proper wick and have many questions on proper methods of getting the ohms right per head, versus wire and wick sizes etc. Can anyone help me out with this? Or maybe have a discussion on related issues, or any other tank issues etc. Thanks in advance.
