Hello, welcome to the fun! I started with the 510 and then got the eGo, which suits me great for now. I am working my way through diff set ups on it and haven't settled on a favorite yet, so no help there. Juice is so funny, no way to tell what is going to be a winner from day to day for me. I understand our taste buds keep changing the further away we get from our cigarette days. One thing that's really helped me is getting diy supplies. I make some juice from scratch- really enjoy that- but also can adjust flavors of meh juice. I couldn't vape some of it without adjusting it with some sweetner or more nic or lemon, ect. You might want to try it. Good luck!
