A pound is not a lot, but all of the gear and clothing choices come with weight tradeoffs and an argument can always be made that the heavier selection comes with a worthwhile benefit. Everyone has to decide that for themselves. For me, after reading about waterproof vs. non-waterproof panniers, I decided that non-waterproof panniers with a couple lightweight dry bags inside would do the trick.

Also, to the person who said that an extra 5 lbs doesn't make a difference on the hills, I beg to differ. Perhaps it isn't as noticeable to some people, but for the type of riding I usually do it makes a genuine difference.

EDIT: I also thought about just strapping on a sturdy dry bag to a rack instead of using any panniers, but I was concerned that it might end up rubbing and falling apart or at least getting torn. Not sure if that is a valid concern or not.
