I dont like the rattles of any of the racks I have experience with and the panniers are more expensive than a good backpack. I think I'll honestly pull a BOB YAK before I put panniers on. I would much rather be a loaded pig riding a nimble bike.

There are a few bags I liked the look of in addition tot he one posted by nahh from STP:

Riding a CX style bike and in the drops I bet the top of those bags will hit the back of my helmet and drive me bonkers.
