I line up with Aimless: sleeping bag is a random jam, no sack (unless prolonged rain is in the forecast), compressed as much as needed to fit in the rest of the load. Next is my rolled NeoAir and any clothing I won’t need during the day. Next is food and kitchen, against the back of the pack, with the tent (in its long narrow sack or two smaller sacks) filling the space between the food/kitchen and the front of the pack, locking it in place. A sweater or down jacket goes on the very top, in case I want them at breaks.

Rain gear goes in the top compartment, readily available. Water filter and spare 2-liter container in one side pocket; another 2-liter container (with one liter of water) in the other side pocket; sit pad, first aid kit, map, and other small stuff in the front pocket. (General pattern: stuff I use during the day outside the main compartment and stuff I'll use in camp in the main compartment.)
