Simple encumbrance house rule

[Elestril]

My house rule for encumbrance and weight tracking,

The goals for the Heft Encumbrance system are:

• Inventory and encumbrance can be easily tracked on a piece of paper without any math, and without getting in the way of the game.
• Heavy and bulky items lead to a realistic encumbrance
• Encumbrance is not only a function of weight, but also of your equipments overall size and awkwardness
• You can’t run around with 7 melee weapons dangling from your belt, just because those are lightweight.
• Only a few large items really matter, there should be a sensible system to deal with all the small gadgets.

Here are my rules for the Heft Encumbrance System, what do you all think? Is there anything like it out there already?
