I have been in love with my Kanger Mini Pro 2's for some time now but I have a question about the Ohm's of the replacement coils for you vets out there. Is there a big difference with the resistance of the coils? I am using a VV VW Ego V3 Mega and have had good luck with 2.2ohm coils but if there are benefits to using greater or lesser resistance coils then I am up to the challenge!
