There are a lot of nice packs out there. My Mariposa plus is older and does not have the curved stays, so, it's max comfortable load is about 25 lbs. I think I had 28 lbs. when I had 8 days of food in it. My brother bought a Six Moon Swift 10 recently and liked it a lot. He had the same pack you are selling on our JMT hike and now is using the Swift. My base weight for the JMT was 12.5 lbs. My base weight for our Sierra hike a few weeks ago was 10.5. Less clothes, less liquids, and my son carried the tarp!

I spoke a bit about food. Food is hard. How to get the best calories per ounce? How to not get tired of what you brought, etc. My typical diet during the day would be Carnation Instant Breakfast mixed with dry milk in the morning. Maybe a breakfast bar to go with it. Snacks like M & M's Peanut or plain, Cheeze Its, Pringles, Trail Mix, Nuts, Snicker Bars, Pay Day, etc. High calories for the weight. I also added Perpeteum from Hammer Nutrition on my last long hike a few weeks ago. Not what I eat at all at home. Works well on long trail days.
Headnets are light and can let you do your chores around the camp. Deet works but I try and use it sparingly. It's real strong but great when needed. The headnet just lets you keep them at bay while eating, etc.
