To be honest, most of these recommendations are reconfirming the opportunities that were nagging the back of my mind....That is:
The Tyvek ground sheet isn't just heavy, it's also a bit bulky compared to a lot of the items in my pack. I was in the basement yesterday eyeballing the window insulator kits that have been sitting there since I moved from Illinois (pretty much unheard of here in Georgia). None of them are cut large enough, so I may see if I can find one at Home Depot, or just pick one up off of Amazon, cut for a patio door.
I hadn't thought about repackaging the Aqua Mira, though it makes sense...I'm carrying enough to purify 30 gallons on a long weekend trip...I had thought about repackaging other things, like the bug lotion, which I am carrying way too much of...I'll probably shave some ounces here.
The dreaded pack towel...it came in handy on one trip (crossing a freezing stream last November and dried everyone's feet). That's really the only reason that it's survived this long in the pack. The bandana does double duty as my water prefilter. I think it may be time to say 'thanks for the memories' and 'goodbye'.
The potty trowel has never been used. Ever. There's always been a better alternative. I have to finally admit that if I really needed one, I'd probably be willing to find a stick to dig with.
The Big Zip Platypus and the Pack. I have to admit that I am aware of lighter alternatives to both of these. I love the way the pack fits, and the Platy has always treated me well. I think that I would be willing to replace both, but not until I tried a friends' and confirmed that they are equally comfortable/convenient. I have access to a GoLite Jam (friend's pack), and I will definitely give it a try (easy pound to loose). Any recommendations on the bladder?
Fuel: I counted the fuel...guess it's a consumable, but I always carry it. So 'base weight' would actually be 8oz or so less, as I carry it in one of those 8.8 oz plastic water bottles they set on your seat in the first class cabin on Delta. They're just the right size for me, so I always stick them in my carry on when I get off. I pity the flight attendant that tries to take them from me.
And no, I do not make the womenfolk carry any of the tent, it's my concession to being the husband/father. I may not hunt on the trail, or even gather berries, but I carry the tent and I carry their food.
Regarding the pot lid, pic attached as requested. This Ti pot came with one of those 'frying pan' lids, which is bulky and heavy and never used. I made this one from some 3/32" thick polycarbonate that I bought at the hardware store. Just cut it out, drill 4 small steam holes, and attach a piece of cord for the lifter. Works swell.
