hey guys, I will be purchasing a reo grand here shortly, and just had a few questions. will start out by saying that I have been vaping for 2 years and for the past year genesis atomizers, with porous ceramic being my wick of choice. I really do enjoy the genesis devices but have to say they do have an inherited flaw, flow back of vaporized juice into the tank, which effects flavor, and this is why I will be giving the reo a go go. I had always liked the flavor of regular drippers but never liked dripping, so that's why I moved to cartomizers, and then ultimately gennys . so the bottom feeders sound like the best of both worlds, and from what I have read the reo is the best. I don't think I would do an rda without a bottom fed device, so a reo is a must for this rda thing to work. anyways, now to the questions, how many of you that did other set-ups before the reo, now just vape nothing but their reo's or do some of you still vape other devices and the reo together? im just wondering if once I try the reo, I will be selling off all my other devices to buy more reo's? and lastly, currently I vape between 13 to 20 watts on my gennys, I do have 1 vv device and 3 mechanicals, so I would have to say that my resistance sweet spot is about .7 to .8 average, so will this mean that in rda's this will be about the same? or is the delivery of vapor & nic different in rda's in the way it feels compared to an rba? thanks for the replies, and look forward to talking to some new people in this thread.
