Hey new backpacker here

I've been looking at potential bags. I want something for overnight, multiday, and even extended trips

I think I will use lightweight, but not ultralight gear. I'm thinking a 12 lb base weight for summer, 15 for spring and fall, and 18 for winter.

I have narrowed the company down to Osprey, because they seem to have very comfy, but reasonably priced stuff. Here are the bags:

Osprey Talon 44: fully featured, breathable, carry capacity 25-30 lb, weighs 2 lb 6 ounces

Osprey Hornet 46: Barebones, not breathable, carry capacity 20 lb, weighs 1 lb 10 ounces

Osprey Exos 48: some features, breathable, carry capacity 20 lb, weighs 2 lb 8 ounces

Osprey Atmos 50: Fully featured, breathable, carry capacity 30-35 lb, weighs 3 lb 2 ounces

Osprey Exos 58: some features, breathable, carry capacity 20-25lb, weighs 2 lb 10 ounces

Osprey Atmos 65: Fully featured, breathable, carry capacity 40-50 lb, weighs 3 lb 9 ounces

Which bag do you think could handle 4 seasons, all trip lengths, bear canisters, and luxuries like books and camera gear the best? I don't really want to buy multiple bags for different uses, because bags are expensive!

Thanks!
