Hi!

I think one thing that should be a game changer is a good backpack that has support and attachments to your chest and waist. Also having the down jacket and a light rain cover is enough. Depending on the season you might not need the sleeping bag and I only bring a blanket when I'm not planning on hiking for days, it becomes unnecessary and is very heavy. I personally don't carry knee braces, ground cloth (i do bring an inflatable pad) poles and i have one thermal layer that i wear under all the time, if there's a river i just try to wash it a bit every night. Hope that helps at all
