Although, I think we also need to have a little discussion on what constitutes minimum gear and what is "taking extra". I think the standard GUE config is a good baseline
Is taking two backup lights on a reef dive "extra"?. I would have at least my two back up lights on my chest regardless of the dive-maybe to poke around in holes, or whatever.
Typically, the only thing that changes on dives for me is pocket contents and that's mostly the number of spools. In a cave dive I have 2 safeties, plus jumps, plus backup jump. That could easily be 6-8 spools between the two pockets. In OW, the spools get dropped down to 2-3 plus primary reel. There can be small variations but 95% of your gear should be the same from dive to dive.
