So I've entered the Pitt, lost all my stuff, and have just got the 10 Ingots for the dude who asks for them. I know that getting more of them in units of 10 gets you more free stuff. My question is when I should I do them all?

My quest update is telling me to go back to Midea to progress the quest. But do I want to get all the Ingots now, or wait until later? I don't really want a full inventory of stuff if I've got other things to pick up during the remaining quests, and I don't want to leave the Pitt without the goodies.

Any thoughts/comments etc welcome.

Thanks.
