Very welcome wigglr, AW IMR 18650's are the best battery around IMO, excellent "C" rating (ability to handle a constant high amperage draw)
AVS i had a long time ago, i remember the best results i had were with carto's (with a hole punched in the side) but there are some very knowledgable people on here who have the AVS down to a fine art, i'm sure they will be along with better advice on this than i could give, hope you get it vaping great soon
