You don't gotta fill a 3 liter bag full everytime. Just fill it half full if thats all you need. There are times when its nice to have the option to carry 3 liters though. I would rather have the option to haul 3 liters when needed but only fill a liter if thats all I need at that point than only have a 2 liter bag and at times wish I had 3 liters when I know I am leaving the valley floor all day on a hot day.
I also MUCH prefer the inline filter as I drink to the stupid squeeze bag. Takes forever to fill the bag with that little opening....then you gotta squeeze the bag to filter in the main bladder. Much faster to just open the a platypus big zip and fill it instantly toss it back in my pack and filter as I drink.
