An issue I have with the design of this one might be fine for tootle puffers (MTL), but it certainly wouldn't do for my long slow DLH's. This little topper is going to get quite hot from the long draws on my preferred low Ω builds. So juice wells that hold excess juice that will boil and degrade instead of letting it be pulled back into the reservoir is a no-no for my vaping style. To me anyway, getting excess joose back out is another benefit of squonking BF RDA's over dripping RDA's.
