If you have the funds, the tipis are pretty awesome for the weight. I went with Seek Outside with a liner because of the sod skirt (a 4" flap of fabric around the bottom that seals out drafts). Kifaru stuff is bombproof too. They both offer titanium stoves that are super compact as well.
Instead of that 51 pounds, you can get:
one of the tipi shelters, stove, pipe,
plus a kuiu chugiak rain jacket and pant, a Kifaru Lost Park Parka, Simms wading pants, Simms wading boots, x-therm sleeping pad, Marmot 0 degree sleeping bag, Sea to Summit pillow, 100' of paracord, Havalon knife with spare blades, MSR Windburner, 2 8 ounce fuel cannisters, a Toaks Titanium spoon, 2 pair of Darn Tough socks, 2 rolls of toilet paper, a Sitka blizzard Beanie, a blue, 8x10' tarp, 20 Mountain House meals, a pair of Mechanix gloves, a pair of Kuiu Northstar gloves, 48 packets of Starbucks Vias instant coffee, a 16 ounce jar of peanut butter, 3 Bic lighters, Fiblink 4 piece fishing rod, Abu Garcia reel, a deck of cards, and still get 5 cans of beer in there.
