Awesome guys! I can only add that when I use 1/4" (or less) plywood, I generally sandwich the foam with it on the hinge side. I tend to put a 1x4 up to whole wall-ID-size inside along the bottom to reinforce the threshold against clumsy feet. I also go beyond fender washers - which I do use, but add 2.25" heavy-ish but somewhat flexible washers I make with a hole-saw from sheet plastic (think thin "camping" cutting board material or...)... also considered painting stepped-on soda cans... but... nah.
