jet boil fash or [jet boil zip](sr_1_2?s=outdoor-recreation&ie=UTF8&qid=1493793538&sr=1-2) yes you can use an alcohol stove and depending on how much fuel you take it can be lighter than a canister stove. But the speed at which you can boil water with a Jetboil is incredible.
titanium spoon sporks suck as both a spoon and a fork go with just a spoon. The polished end on this one will reduce food sticking to it and the long handle can get to the bottom on mountain house bags.
I've never used a sleeping bag liner so I can't give an opinion on one.
For under quilts, sleeping bags, and top quilts I recommend looking at small "cottage" shops. I'm a fan of enlightened equipment myself. I think that is where you may find the best bang for your buck.
Trekking poles i like leki corklite but my experience is that you will fall eventually and there is a chance you will land on your pole. A carbon fiber pole will break before it bends but I have hiked with e bent pole before. I like the side lock over the twist lock because it's easier with my tent. And cork handles are a must for me. Rubber handles suck when it comes to sweat. Also you don't need shock absorbing poles.
Hope this helps!
Inflatable sleeping mat This thing rocks!
Inflatable pillow It's not made for everybody, but its comfy enough for me. Sometimes I use clothing as a pillow depending on how my neck/back feel from hiking.
Jetboil Flash I use it to boil water mainly (coffee, instant oatmeal, instant rice, etc.) If you cook stuff in it, it can be hard to clean... but it also comes with a stand so you can use other pots/pans.
Pack Towel Many uses outdoors, and washes well
Hammock with net This only fits one person, and can be tricky to set up. I use some sticks to spread apart the guide lines for the bug net, or flip it over and don't worry about the bug net. Works great for the summer months - my butt gets cold in the spring/fall.
Cheap dry sacks These don't compress too well, but they work fine for keeping clothing dry and organized.
REI half dome 2 tent I haven't bought the footprint yet, but it's worked great over the past year without it. Longest stay was 10 nights, in January with some rain (east NC) , and no issues with the tent at all. Can get cramped with 2 people plus gear inside... so we just put our oacks under the vestibules and it stayed dry. 6 month old lab stayed with us and did not damage anything.
