Hi Everyone, I'm relatively new to the ecig world having been using a Vision Spinner 2 battery & an Aspire K1 tank for the last 3 months. I've just invested in an Innokin Coolfire 4 mod with isub G tank & 0.5ohm coils. My question regards the juices I've got. I've got 2 bottles of pg10,vg90 which seem very thick & with not much flavour, & a bottle of pg30,vg70 which seems much better. Should I generally be looking a getting the 30/70 mix? If so, how do I use the 10/90 oil as I don't want to waste it. Many thanks, Iain
