What are your must useful, but maybe not as talked about perks and traits? Like Jury Rigging and Better Criticals for example. Everyone loves those obvously.

One for me is Hand Loader. I will never play this game without hand loader.

I've also started watching the show Firefly again, so i am thinking about doing a Malcolm Reynolds character with good Charisma and good with Revolvers/Pistols. Will be light armor obviously, but I was wondering what would be some good perks or traits to go with that. I'm thinking Fast Shot and Built To Destroy. Light Touch obviously, and eventually The Professional.
