I have a few of questions so bare with me if you can. I just started to dip my hands into rba's and my new vv/vw device just crapped out. At first I was thinking I'd suck it up and buy a provari and then I found out that vv/vw devices are actually not the best for rba's. So now I am shifting my gaze to mechs. My only RBA is an AGI and I am a little bit concerned about how this genesis atomizer will work with a mech because I read that the center coil has some resistance to it. I am thinking it may be hard to get the coils below 1.0 -.7 ohm? So now I am looking for mechs and I have no idea what I am looking for. My friend uses a GUS which I assume would be good if I could find one in stock. Everywhere else I've looked I was merely going off of appearances which seemly cant be the best strategy. So I am wondering what are some features to look for in a good mech? Amp limit maybe? However many sites don't list amp limits and amp limits on a mech is still something I don't fully understand. Wouldn't amp limit on a mech come from the battery? Anyways I wan't a mech that fits an 18650 battery, that is well built, and that will complement my AGI. Also I don't particularly like the mechs with protruding buttons. Thank you
