I too keep a couple of sets of armor, jewlery, and weaponry in my bags. Too keep it all straight I even made an excell spreadsheet with each item and its slot, stats and resists listed. So if I need (for example) poison resists I can just sort on that column and all my equipments with poisons resists will line up from best to worst. I also keep a printed copy, in case I dont have time to fiddle with excel during a raid
