I cut down to 2 to 3 inches. The rest remain in the woods to "season" for the firepit. Whenever I want to build a fire on the patio I cut the remaining small stuff and load the tractor bucket. Not that I wouldn't keep and cut the smaller stuff more often, but larger trees=more wood faster. Busting rounds once on the 4-way makes for productivity. If I spent all day cutting limbs, I'd have a backache and little wood to show. Having some equipment helps as I get older.
