Hey everyone this is my first post. Its been a while since I've done any backpacking (10-15 years) and wow has the gear changed and I'm trying to get acclimated.

I got rid of my old pack as I never really liked it, it was always too big and too heavy. So now I'm looking for a new pack, one that lightweight and comfortable, big enough to carry my older heavier gear, but small and light enough to allow me to eventually get to a light weight status.

My trips will mostly be long weekends, I can't imagine a trip over 1 week. What size packs do most people use and recommend, 30L, 40L, 50L? I think my last pack that I disliked was 70L.
