No need to take stove or cooking gear, but emergency shelter could still be a good idea - especially if you're carrying a sleeping bag anyway. Always a chance that weather or mechanical problems keep you from reaching a planned destination and you may even want the shelter during the day to wait out a bad squall. My tent (1-man) weighs under 2.5 lbs and my mattress pad another half lb. so I'd only save 3 lbs. by leaving them behind. Using a tarp or bivy sack would weigh even less.
