Ok guys- sorry to pound on the dead horse, but here goes:
I'm in debate between the WE Lost World (115 litres) and the Karijini (90 litres). The only reason why I'm considering the bigger pack is because of my duties as the family pack mule. I'd like to be able to do a 8-nighter in Summer out of hte pack. I think after al lthe debating and searching we're going to get a WE Breakout for the wife, so she'll be carrying the big light things like the sleeping bags and air mats, and the camera gear and a bit of water. Here's what I'll be carrying (clothes and food are for two adults and a kid):
Pocket Knife
20 Metres of Nylon Cord
Whistle
Zip-Lock Bags
Rubbish Bags
Waterproof Matches
First Aid Kit + Medicine
Headlight
GPS/EPIRB
Coleman Phad X3 Tent (3 person with good-sized vestibule)
Food in separate bags (for all of us)
Kovea Stove and Lantern (Butane)
Polycarbonate Utensils + Dish Sets x3
Pack Towel + Face Washer x3
Cup
Plastic Trowel
Toilet Paper
Tooth Paste
Camp Soap
Tatonka Cook Set
Pot Scrubber
Bulk of Clothes for all three of us
MAYBE 1 synthetic sleeping bag, a light carbon fibre tripod and ball head, and 1 litre of water.
I reckon a 90 litre pack would be enough, but I'm not sure. What do you think?
