I dont bother with a secondary either. If dry hopping, i like to wait till fermentation slows (3-4 days) then toss the hops in the primary. The light fermentation activity helps carry away the O2 in the hops. After dryhopping i may transfer to another carboy for a day or so before kegging to make sure i dont pick up any hops. Nothing more frustrating than sucking up a hop leaf clogging the pin lock.
