I'm going to be stuck using my vision spinner 2 1600mah for a few weeks until I can order the authentic eleaf Istick or a mechanical mod clone. I'm going to have my kayfun clone from fasttech, and will be building with 30 gauge kanthal with cotton wick, what would be a safe Ohm rating to use? Would a 1.5 ohm coil do fine with this combination? I'm not looking to get the most massive clouds, but I would like to get at least a little better than my mini protank 2, i'm just tired of buying coil heads because I like the hands on factor of an RTA. Thanks
