I decided to edit the .lua file a little so that I could make little spikes of vertical health bars for my raid. I only used Grid to see whether or not everyone was dying/taking intense dmg so that I could predict a wipe, and I decided to nix Grid because it wasn't necessary and I didn't like how, no matter what, it was going to be too big and awkwardly placed in my UI.
I like the results, except for the fact that every single frame has that translucent background...I like it on most of them, just not my raid/party. I want the little spikes to not have that frame background.

I know next-to-no LUA, but I do know how to delete or edit sections of code. I didn't seen an option in PitBull's config to disable the frame background, though I could just be helplessly blind. I didn't see anything asked about this specific issue in this thread, but considering I read it at work in between boss sightings, it's possible that I missed it.
Anyone have a simple or not-so-simple answer?
