Extractors, because I like their simplicity. When walking up on a dog on point, I have a shell or two between the fingers of my forearm hand (primer end towards the gun), so it takes almost no time to reload, and I don't have to worry about cupping the empties, and I just tuck them in my vest for reloading. If the action is fast and furious (i.e. quail), I grab extra shells from my left vest pocket with my left hand, due to less wasted motion.
