Exos 46 or 58?

I have the 58 and really like it. Keep in mind that you can leave the top lid if not needed and save 4oz.

I've been using a 58 for a few months now. I can't afford to keep an assortment of packs, and the 58 actually works well when not very full. I cmpress the main bag and put my pad between the bag and the hood. Balances out very nice without weight settling to bottom. It also allows me to store stuff uncompressed when I don't need all of the room.
