Yes, I've been using this mod for a long time, very well done and useful. Although I think I tweaked the colors a little for personal use, but still better than default by far.
I'd actually take the decals over fire, but fire would be very close behind, as well as an abstracted hand to hand system, although I'd take decals and fire over that any day.
Yeah it seems there is a set that was introduced in MG that is now unmodded. I think I noted it in an earlier post as well, they really stick out compared to Aris' current awesome work.
At this point 50/50 or more sounds awesome to me. I'll take it, can't wait to see the graphics end try and catch up with the under the hood mechanics side.
You could try mixing in a few with and a few without and lowering the volume of the reloading sounds on the ones that are in. That might be a good compromise.
