I've never needed a list and don't weigh my pack.
These lists to me are like the husband and wife backing in a travel trailer at the campground with headsets and back up cameras. Takes twice as long and you end up in the same spot. I kind of just set my lawn chair up and chuckle.
I haven't ever packed in too heavy and haven't forgotten anything.
I leave my gear semi packed so its confusing how many people stress about being organized. These lists make me think you hide everything on yourself spin around on a baseball bat ten times and then try pack your bag.
