EDC is just that every day carry. What I pack in my kits does not get used every day, it's not supposed to. I have the most redundancy w/ first aid kits and I'll grab the bigger kit first when possible to leave the small kits in tacked. I do have several different EDC set ups. Home, work & woods play all differ to some degree. The most redundancy is built into my wilderness kits and yes I do add some things in there before I go but it's only 2 or 3 items.
