The Deuter bags are great. They have a good system for keeping your back cool and dry. Obviously you'll sweat a little, but it's remarkably good.
Plenty of neat touches, and they take hydration systems. I've got the 'Race' version which is great, and it has a rainproof yellow cover integrated.
Don't listen to the rack fans, why put weight on your bike and affect the handling, especially if you weave in and out of traffic. As for me, after minimizing everything on the bike, a dirty great rack would ruin it...........
