HYOH, I say. The evangelistic fervour in the lightweight "movement" is rather odd, to say the least. What that dude I meet on the trail chooses to select for his trip is none of my, or your, business. Perhaps we will chat, and perhaps the talk will drift around to gear, and what works in this region at this time of year. Maybe it won't….
The thing about preparing a pack for a trip that appeals to me is elegance – getting just the right stuff,in the right quantity, for the objective. Thus the pack may be heavy, or it may be light. Depending upon the trip, i have carried anywhere from ninety to ten pounds. I have always been attuned to information about something lighter that would work as well or better than my current gear. Before the internet, the principal source were conversations in the evening around a fire and that is still a pretty good way to communicate. Hopefully you are comfortable and well fed as you extol the virtues of the light way.
Does the One True Church have a messiah yet? How do you get to the Temple from here?
