Thanks for the ideas. I figured that the biggest step for me is to replace my big 3 with truly lightweight options. I'm perfectly willing to sacrifice some comfort and switch to a tarp instead of a tent, I just haven't gotten around to buying one yet. Honestly, the last time I went backpacking, I was more comfortable under the tarp we used than I've been in many tents.
I think I need to get lighter rain gear, since my current stuff seems on the heavier side. Any ideas for a cheap, lightweight, waterproof/breathable rain jacket?
I can probably lighten up my insulating clothing as well. Right now I'm just using what I happen to have as far as an insulated jacket. I'll probably replace that jacket with either a ~5oz synthetic vest or a <=10oz synthetic pullover and gain significant warmth from the switch, since that jacket is honestly terrible. I might go the MYOG route and make either a Thru-Hiker Minima or Kinsman, although I don't currently have access to a sewing machine.
I think that at some point I'll probably make myself an alcohol stove as well, replacing my heavy MSR Reactor. At that point I'd probably buy a lighter pot as well. I'm not quite ready to shell out for titanium yet, so are there any good options for a cheap, light pot? I'd probably just be using it to boil water.
The weight listed for the Hubba Hubba on my list is my measured weight of the fly, poles, groundsheet, and stakes. That is, it's the weight of what I'd plan on carrying for the lighter-weight option, setting it up without the mesh tent body. Does it seem too high or too low?
