Your comments will be worth waiting for. I look forward to them.
I have one RM7. Now, I am not an original thinker when it comes to REO's and atomizers. I rely on those who put in a lot of time and thought, if you are a regular here then you know them. I'll unintentionally omit someone if I try to name them. So, my comments below are those of a mere user, not those of a thoughtful person. [Kinda like my truck, I can use it with skill but don't ask me tell you how or why it works.]
I find the RM7 superior, for my purposes, to Odin, Derringer and a myriad of others. The reasons are similar to those that you state. My taste buds, having tasted for seventy years, may be as worn out as the rest of me; so, for me, taste is fine - as is the vapor. Its superiority to me is in the mechanics.
I would have to intentionally over squonk - it could be done but I would have to work at it. It is probably as leak free as an open atomizer can be, no matter in what position or angle I use it. I can set it down on any of the five flat sides without a leak. I like the very free draw, much like Derringer without the runs, drips and errors. The build deck is very easy for old eyes and hands. Coil placement is not as critical as it is with others. Lastly, the coils sit at such height that re-wicking is very easy without disturbing the coil form, again old eyes and hands. Working with the coils I find easier than I do the Odin.
I hope some find this post helpful. I will be ordering another of this style, whether it is an RM7 or an original, I await Rule62's comments.
