Hope maybe to take some learning curve out of the process. So far, I bought and returned a Blu kit, bought and kept an Ego and a 510 kit, for me and my wife. We like the battery life we get out of the new Joytech stuff, and it came with a bunch of modification stuff. I have settled into using the Ego's, she likes the 510's. We both use 510 Low Resistance atomizers, with cartridges. I use the blue foam for cart filler, works well for wicking. I also got a tank system for both the Ego and 510, but neither of us like the tank systems. Too much air, we get better hits off of the 2 piece atomizers and cartridges. Without spending a ton more money, is there suck a thing as a tank system that hits and produces vapor like the 2 piece atty and cart system we use now? It is a pain in the .... refilling the cart all the time, so I would like the convenience of the tank system, but like I said, the Ego and 510 tank systems both have too much air for a good hit. Is there anu system we could use with the Joytech batteries we already have and like? Any and all suggestions would be appreciated. Don't want to spend the next month on the learning curve all over again, it gets expensive and time consuming. Thank you in advance!
