Why run both BigWigs and DBM?  I’m currently evaluating which is the better raid mod.  I’m leaning towards BigWigs.  KTM and Omen have been duking it out forever.  I prefer to use KTM, but since Kenco isn’t as diligent with updates, I settle for Omen.  The list may look menacing, but everything is modular so there are lots of folders that belong to a single mod.  I’ll add a screenshot of my UI later because even with the incredible list of stuff, it’s fairly clean.
