Hi all, up until recently i've run mostly clearomizers (i still like them and cartomizers for when i'm out) but i figured i'd take a shot and get a cheap rba. I bought myself a pheonix bully and all i can say is wow. So much more vapor production and way better taste. It holds about 5 to 10 drops of liquid so i'm not constantly dripping. My question to the more experienced folk is where should i go from here. I have a good working knowledge of electrical components (electrician) so i'm not worried about getting in over my head that way. Do all rba's need to be kept upright or are there ones that can take being carried around in a pocket at work. Any help or tips on what i should be looking at getting to bring my vaping to the next level would be greatly appreciated.
