Do you have any further critiques for the gear list that I posted? How about what kinds of foods you're packing to save space"
I missed your gear list post. My bad. Some thoughts: Pad-maybe a Neoair, which is much less bulky and lighter, paired with a GG thinlite, or a Montbell 36" inflatable(less bulky and lighter)also paired with a GG Thinlite; sleeping bag-possibly a WM Summerlite or Marmot Hydrogen, to name a couple. You can order the Summerlite with overfill to take it down a few degrees, IIRC. Either of these, augmented by your clothing, would provide a lighter, less bulky sleep system; down jacket-possibly a Montbell Alpine Light Parka or UL Down Parka would be lighter and less bulky than a Fugu, which is overkill for 3 season use, IMO; a pair of 1 liter soda bottles would be lighter than a Camelback, and would fit nicely in the side pockets of your Circuit. If you eliminate the Ridgerest and stow the inflatable sleeping pad inside your pack, you could easily carry your Duomid on top of your pack, freeing up the side pockets for your water bottles. The fly rod could be carried inside the rolled up Duomid on top of your pack if it is not too long, or lashed on the front using the ice ax loop and retainer with a little ingenuity, or even still be carried in the side pocket behind a water bottle.
Food is long discussion that breaks down along the following lines: 1) Cooked or cold food. 2) Type of food that is palatable to you. 3) How much food is sufficient. 4) How the food is packed.
Personally, I no longer cook my food, but do bring a stove when packing with others to satisfy that almost universal craving for hot coffee in the morning. If I'm going solo, I just take a bottle of water to bed and settle for a warm cup in the morning.
I find a broad range of ingredients to be palatable, if not gourmet, and end up taking granola, Nido, coconut, coconut oil, chocolate, various chips, crackers, sesame sticks, nuts, Hammer Perpetuem, and Starbucks Via. I combine these ingredients into breakfast, lunch, and dinner ziplock baggies, and crush all ingredients in order to reduce the volume as much as possible. They can be eaten out of a baggie with a spoon. Crushing the food is very important if you want to get as much food as possible into a relatively small pack.
I aim for ~135 calories/oz and carry just over 19 oz/day for a total of ~2600 calories of carried food. This is supplemented by 3-4# of body fat to provide the ~4200-4400 calories I burn per day on a typical 8 day trip in the Southern Sierra.
I based my earlier post to you on my experience with kit and food as described above, all of which fits in an OHM with room to spare for trips up to 11 days. Based on this I am pretty certain you should be able to fit everything for a 7 day trip in a Circuit with some adjustments to your gear and food. You might consider experimenting with the food first because that alone might do the trick and save you the cost of buying new gear.
