I'm part of the anal-retentive crowd, I guess. All my fired brass gets tumbled, then sized. For the cases using a FL sizing die, I throw the majority of them back in the tumbler to remove the sizing lube. Slowly collecting neck sizers though, and for neck sizing, I usually use graphite or nothing, and only rarely bother to do any wiping after that.
I try to police up others' brass where I shoot, which is always out in the sticks, and there is usually some varied handgun and rifle brass lying around. I stockpile and eventually sort by headstamp, then prep it and work it into the shooting mix.
