Going to be buying one of these for my venture into rebuildables. Looking at pics here and elsewhere, I'm seeing some odd looking combinations. Big gaps, different finishes or diameters, etc.. I want to find a mod that will look right with the tank. I'll be happy to spend $ for quality. If it's a mechanical I would like there to be room for a kick. I will be dipping into the sub-ohm territory, so that must be considered as well. Thanks for your suggestions (and pics 
)!
