It is obvious that there is often evangelical zeal to be UL or SUL here on BPL. Sometimes it gets down to "the right way" only. Often members will post questions, seeking help or input, and they are belittled for not conforming to a certain mantra, and sometimes a lot of useful options are discussed.
I work for a consulting company. We help businesses to improve their profit, grow their business, and make their customers completely satisfied. Sometimes our entry point is to focus on a small target area of the business, or to deliver a large comprehensive solution for the entire business operation. The goal for us is to deliver the solutions that results in the client's desired outcome. So here is how we go about it ("Cliff's Notes version").
1. What does the client seek or want. (GOAL)
2. What is the current state. (What works, what is in place, what is not working well)
3. Are there other opportunities for improvement the client has not identified.
4. What high level attributes should be in place after we are finished.
5. Can we finish the project with a method for the client to sustain the changes and enable them to go down a path of continuous improvement.
6. When we are working as change agents, we want to determine the key attribute needed within the organization's technology, facility, people and culture. That is, how do we develop effective solutions that are aligned to industry best practices, and are also customized to the needs of the business.
7. The solutions for two very similar organizations may look very different, but the key attributes are in place at both of them.
This approach works for backpacking too.
1. What is the backpacker's goal (this REALLY varies among people).
2. What gear is currently in use, and does it meet the goals.
3. What skills are in place, and do other skills need to be acquired.
4. What other gear options are available to the backpacker, based on goals, budget and desires.
5. Do the options make sense to the backpacker.
In the US, Colin Fletcher started the "backpacking revolution" more than 40 years ago. Most people consider him a traditional backpacker. But read his books carefully. He was a gear junkie, and was obsessed with weight, given the equipment and material available at the time. He often probably carried more back-up equipment than many of us here on BPL.
Fletcher popularized the postal scale, and the idea that parring ounces would save pounds. He presents the cliche methods such as, trimming map margins, cut off tooth brush handles, use trash bags for rain gear (e.g. Colin's Kilt), etc. Each edition of his Complete Walker reviewed the new and lighter options. His last edition (co-written by Chip Rawlins) in 2002 even had references to (gasp!) Ray Jardine and Dan McHale, which are two different approaches.
So, set your OWN backpacking GOALS, review your skills and physical conditioning, determine the best gear that meets these goals, your level of safety or risk avoidance, and your budget. If you are a person seeking continuous improvement, consider the alternative equipment and views of those who have good experiences to share.
If your main goal is to go the absolutely lightest way possible, that is okay, but do not force it on others. Playing the gram weenie game is okay, it allows one to test the waters of gear options, and then adjust up or down as needed by YOU.
There is no "right way" to do it, other than coming back home safe and alive.
