"I NEED the ankle support"
I feel you. I always wear boots when I'm bushwhacking, so matter how light my pack is. If you're in the market though, merril makes a high-top version of the Pulse that it might be worth trying on, just to see.
"Do you have any recommendations for a lightweight camp shoe for someone with a large foot? "
Search camp shoes on this site, and you'll get a million MYOG ideas. If you're only worried about camp shoes and not about fording, some flip flops from the drug store will weigh 1/5 of the tevas. I don't use camp shoes, but I got some 4oz surfer's reef boots for fording. They come in crazy sizes.
"I will not take a razor blade to the pack or remove material from any of my gear."
I used to feel that way until one day I noticed that all the straps on my pack were ridiculously long. I lost a quarter of a pound just trimming the straps, and with a hotel sewing kit, I folded the ends over, good as new. If I did it with a sewing machine you wouldn't even be able to tell. Not sure what your issue is with this, but if you're worried about resale, the crazies around here will buy your old pack with mods :-)
"The reason for two fuel containers is one; a little redundancy does not hurt – ever hear of not having all your eggs in one basket is a bad idea? Well if one were to leak, I’d be able to continue to cook without issue for the entirety of my trip."
Part of going UL is relying on skill as much as or more than gear. Choosing the right equipment- even containers- eliminates a lot of the redundancy associated with traditional backpacking technique (this is a HUGE part of UL mentality). A plastic bottle from REI can hold as much volume as the bottle you pick and they're quite butch. Besides, even if you did have a leak, the dryer lint in your first aid kit will serve you to start a fire for emergency heat. You'll live without outmeal til you can make it back to civilization.
"Don’t want only one water container on a trip. A leaky container could lead to problems."
See above. I suppose you COULD break a flexible nalgene bottle, but seriously? You can drink out of your pot. Besides, if the platy doesn't mate with the steripen, how does it serve as a backup? 2 wide mouth gatorade bottles weigh less than 3 oz. Speaking of redundancy, you might want to toss in a day's worth of micropur or other water purification tabs, just in case the steripen goes awry.
"Dri-Ducks won’t stand up to much bushwhacking from what I have been reading"
That depends on the user. It might be worth it to try a set out for yourself, even with a backup trash bag-poncho it would be a huge weight savings.
"Need to find a place that has size “fat” in stock"
Keep your eyes peeled on the clearance racks at REI, EMS, etc. I have a frugal eye, and I see a lot of good stuff in XXL there. There are a couple of Marmot windshirts on clearance size XXL in my local REI store right now, there may be in Ohio, too.
Nice list, good luck!
