Ok first of all I'd love to share a "trick" I read on the forum a long time ago. It's about the Provari. As most of you probably know it will shut down the firebutton when it's electronics think you should charge your battery. Actually it's not a good idea to cut out safety mechanisms, however, if you screw off the part where your battery sits and then again put it back in place the Provari will fire without any complaints. This is pretty helpful when your battery dies while you can't charge it or have no backupbattery with you. I hope you get the idea 
Secondly, I'd like to know what you guys do if you flood your cartomizer. I always fill and fill because I'm so anxious to start firing it when it's dry. So one out of two times I flood and I'm never able to blow out all of the excess liquid which blocks the airflow. It will still work but sometimes the draw can get quite stiff. Any handy tips available on how to clean the hole easily in order to maximize the airflow (apart from not overfilling it
PP)?
