Hi guys. Well, after hearing all this ranting and raving about them there rios things, curiosity got the best of me so I ordered one along with an RM2. I'm really excited to get it, going to be a long few days waiting on the mail. Like many, my path was quitting analogs, ego starter kit, then vamo v5, mvp 2.0, provari and KFL+, now I'm here. I'm hoping that this ends my search for the perfect vape 
So, now that I've got one headed my way, I have a few questions:
1) After moving to a KFL+, I noticed the 18mg juice was way to strong for me, as it seemed to deliver much more than the protanks. So I went to 12, which os good most of the time, but I even have some 6 that I'll mix in from time to time. Did you guys find you needed to go down on nic level when you went to BF style mods?
2) I've never done sub ohm. In my KFL+, I tend to like about a 1.8 - 2.0 build using 28g kanthal and organic cotton. Much lower and it looses flavor and burns my wicks. I'm assuming, being a mechanical, I'm going to need to go lower with the build. Any suggestions of where to start? I know enough to use an ohms law calculator, and decent AW high drain batteries, etc. I have no desire to cloud chase, mainly interested in flavor. What's a good starting point?
3) How do you know when to replace batteries? I've read going below 3v will trash the battery or worse.
Thanks guys!
