Here is the video with the cup coil I was referring to and that the glass or titanium insert nail could be put into: Click to play YouTube Video Yes, the Mesh RDA would give you a ton more room than other post rda's and I believe this extra space is absolutely needed to make this work. I don't think the vertical atomizer will have any issues either. I emailed Vandy Vape for the diameter of the mesh RDA and will update on if we can marry the sourcevapes bubbler with the rda from Vandy Vape. If we could that would be clutch. For me, the advantage over the usual Source Vape setup is the cost. I could just use regular 316 wire instead of buying their proprietary atomizer. You're not locked in to buying from them. Also, yes, wrapping the coil around will dramatically heatup the insert quicker. I saw someone post somewhere about buying those vaporsource inserts (or something similar), but I can't for the love of me figure out where that was.
