"But if I was to type in "backpacking", the first thing that came up are MEC's and REI's checklists. Not to mention numerous guiding services. Along with Backpacker magazine. From what I can see, the checklists don't really jive with UL backpacking."
Sometimes we place too much emphasis on the UL way. Some people just aren't interested. Some can get by just fine with traditional gear, and many people have done epic trips with traditional gear that many of us will never approach in scope and beauty.
The few people who have hiked with my know my kit is pretty light. But that isn't the point, the point is the enjoyment each individual realizes for themselves.
An interesting dichotomy is me and my son, who is 36 years younger than me. In high school and college he was an elite distance runner. He has run thousands and thousands of miles over the past 10+ years. I get advice from him on running shoes. He doesn't hike in runners, he wants to wear boots, boots that I bought for him. I don't try to change him or convince him there is a better way.
His backpacking gear is "traditional" stuff, much of which I bought for him as gifts over time. I buy what he wants, not what I think he should use. I did give him a ULA Ohm — he prefers his REI Cruiser. He knows I would buy him the latest and greatest cuben shelter and other gear for his birthday and for Christmas. He isn't interested, he has many diverse interests in life, and backpacking is just one of them. In his backpacking circle, his gear is excellent.
My son is a great backpacking partner. We have great times together and we rarely discuss gear, unless I am teaching him how to use something. My light gear and his heavier gear put us on an equal plane — I can keep up with him on any trip.
