One thing I’ve learned over the years is there’s no “perfect pack” you can just have on the shelf to grab and go. Once you get beyond EDC and some core items, everything else is a decision based on season, terrain, number in your party, and so forth. I don’t start those kind of discussions because they become The Never Ending Story.
The real epiphany to me was the shocking lack of even basic EDC items on most hikers.
