I took most of Mike's gear recommendations and made some big reductions in my pack weight. Right now, my gear list is at 9.75lbs exactly--4lbs down from before. I didn't come up with 7 lbs of savings, although it's close to that if you count the weight of the bear canister (which I was only going to carry in the Sierras regardless, otherwise I will hang my food). One thing I did not change was the sleeping bag, mostly due to budget. I recently bought the sleeping bag I listed here, and I can't find a decent quilt for any sort of reasonable cost. However, I'm going to attempt to make my own quilt after some sewing practice, so if that works out I could cut an additional half pound off of my base weight. It's the same story with my down jacket -- a bit heavier than I'd like, but getting the top of the line stuff is prohibitively expensive for me. Anyways, here's the list.
The two big cuts are the pack and the tent. From the research I've done on resupply along the PCT, as well as on the ULA Ohm, it seems like the ULA Ohm could be the perfect pack with this trimmed down list. It looks as though I could do an average of 4-5 day resupply periods (possibly less), with a max of about 6 or 7 days. I'm basing this off of resupply strategies found here and here. I'd estimate that my average "fresh" food supply weight would be about 10lbs at 2lbs per day, with an absolute max of probably 15lbs. So, I would have to think that my total max weight would never go above 33-35lbs (12.75lbs for Sierras gear + 15lbs of food + 5lbs (~2.5L) of water). According to this recent post about the ULA Ohm, the "sweet spot" is less than 30lbs, with optimal being 20-25lbs. One guy even said that he did 40lbs, which wouldn't be ideal but certainly OK for short stretches. Unless there are any major objections, I think I want to go with the ULA Ohm at a savings of about 22oz.
Does anyone have experience with the ZPacks Hexamid? I think that it should be ideal for the PCT, and the added bug protection is nice. Am I correct in saying that a bivy is unnecessary for this shelter? The downside is that it costs about twice as much as the Tarptent, but I think that the weight savings (21oz) are probably big enough to justify that. It also pretty much requires that I carry trekking poles, which I'm not accustomed to. They seem like more trouble and cost than they're worth, but maybe my knees will disagree.
If I succeed in making some homemade down gear, I may be able to get to about 9lbs of baseweight. I'll start with the quilt, and if that isn't a disaster I'll try making a down jacket (using Thru-Hiker's patterns).
I will trust Mike on the crampons issue, since I wasn't too sold on them to begin with. I will need some place to find training for an ice axe, though.
Let me know your thoughts on the snazzy new list.
