I don't normally go cookless, but in the summer for a couple nights it would be fine. or maybe bring a pot and do cookfires? the lighter weight dry food might make up for the pot's weight.
9-11 pounds is a lot more normal for me too, especially since most of my backpacking is either guiding campers, so I take my "heavy" Cilogear 60L, ultralight personal gear, then guide gear, group gear, and food. Or I'll be out for some backcountry rock climbing, so its ultralight personal stuff in the 60L, plus a rope, rack, harness, helmet, slings, biners, maybe some glacier gear, food,.....
