Don't know anything about your setup, but if you plan on doing a lot of wilderness hikes you will need 3 liters sooner or later.Not sure it's the "best" but I have had great luck with my camelbak antidote 3L bladders. My katadyn hiker pro works perfectly with its quick disconnect attachments.
Unless you plan on jumping on your bladder repeatedly in the backcountry, some of the durability features are over rated.
I agree with this guy. Ive now had a few dromedary bags, platypus big zips, & camel backs all leak @ one time or another. Tougher isn't over rated with me.After a second time of completely wet gear and having to dry it out, I wanted something that I could trust. I dont find it overrated at all. That was my motivation. Yours definitely maybe different.
