I lol'd at the last option.
It's funny because in the game's beginning I'm pretty much the last option, if isn't nailed down, I take it. But as the game goes on and you acquire the armors, weapons and wealth you want, I start to select.
I mean, after a while we are pretty much rich, so you don't need to pick every wonderglue, scrap metal, scrap electronics, wrench and duct tape for crafting WRK, you can buy it from the Boomers or you can buy the materials from merchants and if you have Dead Money, you have an endless supply.
After this point I pick the ammunition and money an enemy is carring, that's all.
If I have the Jurry Rigging perk and his weapon serves for repairing mine I take, otherwise I leave it, even if it's an AMR.
