I've done minimum research on them but a lot of the stuff I found pretty much said they were moody and tempers, in other words they're mean, to people, dogs ects. But it would be ok if they were mean on hogs right?

That was my own reserch which was not extensive at all.
It's also all over about pits. And a good pit can't be beat!... Any dog will be aggressive in the wrong hands.
