First place is for traits to actually have an impact. One that might be good is a handiness trait like those folks we know that just have a knack for that sort of thing, almost an instinct. In game terms, they could fix things more quickly and easily and gain the skill faster as well. Would have better chance of finding parts when rummaging. A couple of others might be 'numbers talk' for those who love those detestable things, and 'wordsmith' for those gifted in that area. Either of them would easily impact various occupations, science for the numbers person and writing and politics for the words guru. Probably others as well.
