Same sentiments here, welcome to ECF Mlke. You definitely made the right choice by coming here. Anything, I mean really anything you want to know, someone here has been there done that, and happy to impart their knowledge to everyone else. Sit back, take a deep vape and keep reading (everywhere on ECF) and you'll be enjoying things tenfold. Promise.
And, as for the ohms question, I'll just chime in and say 1.8 is good, really is, but 1.6 rocks. Ya gotta find what's good for you, and the only way to do that is to experiment and listen to the guidance offered by the fine folks here. Again, welcome, and enjoy your vaping!
