Ok, so I just got some HV atties from eastmall today and WOW they work great! They are just a little bit weaker than 6v with a SR atty, but definitly way more intense then a LR at 3.7. I am very happy with them. I even gave them a shot at 7.4v with two 18350 and it was incredible! Just below the point of burnning the eliquid so it produced amazing flavor and throat hit, but just a little too strong. I'm going to have to wip up some 8-12mg nic juice to vape at that level cause the 20mg I'm using is making my hands shake and sweat!! I got so excited that I overcooked my mac-n-cheese lol! The LR atties I got from eastmall are some of the best I've purchased so I am very happy with their products and prices. You just have to save up and make a bulk order so that you can justify the high shipping cost. Only complaint is that they sent me the wrong batteries but hopefully they will respond quickly and send the correct ones without a hassle.
