I use the LotFP encumbrance system; I like it’s blend of doing away with math but retaining a bit of complexity as compared to the very bare-bones systems of “carry STR items”. For my current campaign, this strikes a good balance.
I have made one addition to it, though; the “item slots”. As some players start to outfit their characters with scrolls, potions, weird bombs, poison-covered undead ferrets or green slime jars, things can get a bit out of hand. It makes sense to track at least on a rudimentary level where all this stuff actually is, and how readily available it is.

The back slot may hold an Oversized item. Such items must otherwise be held in the hands. All other Slots hold only Standard Items. Armor adds encumbrance as normal. Any worn items, including armor, is listed separately, and apart from armor they do not encumber the character. In addition to this, any character of course has two “hand slots”, but I find tracking this goes too far into fiddly territory for me. A character with a Great Weapon is assumed to old it over her shoulder, otherwise the hands are most often kept as free as possible to allow for easy movement and manipulation. I’ve changed the rules as we went along to include “stacking” of certain items; for example flasks such as potions, oil or holy water stack two in a slot, iron rations and torches stack three.
This imposes some interesting limits on the characters; they really can’t carry an unlimited amount of items around, especially oversized ones. Pretty soon they will be carrying around their loot in filled sacks, carrying chests between them and running into all sorts of fun.
Tracking this is pretty easy, the players use different methods (and I’m not too particular about it, as long as they keep track). Letters next to the relevant items (Be or Ba etc) works, as does making little sections in the equipment list.
