how well the back pannel manages sweat: Ok I guess. My old backpack caused my back sweat profusely. I still come home with a sweaty back, but it's not unbearable.
Additional Features of the pack you like: MP3 pocket is perfect for my phone.
Features of the bladder/hydration system you like: It's simple, and it works well. Easy to add ice due to the big opening.

What would be the main reason (other than additional fund) you would upgrade this pack or buy a different hydration pack: If I were going to be on my bike for a few days straight, I'd want something with more cargo capacity.
Things you do not like about the pack: I don't like the balloon effect when the bladder is full. It goes down in a few miles though, so no biggie.
Things you dont like about the bladder/bite valve: You kind of have to "cram" the bladder in when you have the full 3L of water.

The whole pack is very practical and usefull. It's pretty well designed and has made my life much easier. Oh, and it looks *****in'.
