Well i just got my first Slim style ecig as i found it cumbersome carrying my VV Buzz around sometimes and i went with a 84mm and 105mm auto batterys from MVS with Standard 808 cartomizers.I really do enjoy it, it just feels more natural and easier to carry.But with all the Buzz on the Bloog it caught my attention as so many have been raving about the BMF cartos.And i will purchase some of those to try out as i am running low on cartos.But For those that have tried the standard and bloog are they that big of difference in battery's.Say the bloog 72mm vs my standard 84 Just looking for insight from ppl that have used both
