This is a simple one that we think is a no-brainer.
Basically 5 + Brawn is a character's base Encumbrance, nothing new there.
Our GMs feel like this should reflect the heaviest weapon(s) and armor a character can equip and wear (including a Jet Pack, for that matter).
We still buy Backpacks and such, but we feel that characters should not be allowed to use their Backpacks and Utility Belts or whatever to use those Encumbrance bonuses to carry heavier weapons and armor.
I mean if you're wearing armor and carrying/shooting a weapon, it's not in your backpack, so you shouldn't be able to take advantage of the extra Encumbrance that provides. We're restricting our characters to a base "Personal Encumbrance" to define what weapons and armor they can wear.
For example, my Gadgeteer has a total Encumbrance of 15 with Backpacks and whatnot, but a Personal Encumbrance of 7 (2 Brawn). He can wear Laminate armor and carry a Heavy Blaster Rifle, nothing heavier, which maxes out his "Personal" Encumbrance
Also we've ruled you can only carry EITHER a Backpack or Jet Pack on your back, never both. One of our players said something about flipping the backpack around and wearing a backpack on his chest and a jet pack on his back.
We laughed and cried "munchkin".
We're not trying to change the rules for Encumbrance, you can still incur additional difficulties and whatnot for Brawn and Agility checks when you're encumbered. We're just ruling that your weapons and armor are restricted by your Personal Encumbrance and can't benefit from the bonuses provided by Encumbrance-enhancing items.
