what notable advantages are their to a dual positive post rda? i am looking to get a new atty that matches the look of my new box but i am considering possibly snagging one with 2 positive posts. does it effect the resistance at all? are their any good 2 positive post rdas that anyone would recommend? i just got the black sigelei 50w. all my other atomizers are either copper or brass and just look out of place on it. im looking for a nice cloud chucker that has a fairly deep well (im in love with my mutation but the copper and black clash big time)
