Yeah, I can see that, seeing that each of the others were specifically designed for one purpose or the other. Although I still seem to get as much as, if not more, vapor production out of my MX as my Plume.
The funny thing is ... I expected to get MOAR vapor from the MX than from the Plume because I believe it is more wide open, but I just don't. Mind you, it so close as to not make a difference, I mean, I'm not competing, but, I just don't get it.
