Bak, whatever works for you is what you should use. You'll find there is a small learning curve when you first start vaping. Take the time to figure out what vaping is all about, get used to and comfortable with your equipment so you can stay off smokes and you should be fine. Don't get too wound up about someone's "opinion" of your setup. Instead, enjoy what you spent your money on. Once you're settled in and comfortable with vaping, then you'll probably want to explore other equipment setups. If/when you want good advice, you can't go wrong right here. Be picky about the shop you frequent, too. Too many shops want you to just buy something and leave. Make sure you know everything there is to know about what you're buying before you leave. You've probably already figured out the combinations, equipment and lingo can be mind-boggling to a beginner. You'll be just fine.
Talk about overkill, I sometimes cruise around with an eleaf 20 topped off with a full size Nautilus. My attitude..... Works for me. If you don't like it, don't look at it.
