Magic
I have the CB Magic. There is a noticeable difference in the straps on the WSD, well worth the extra money. In my opinion, the cooling benefit of staying hydrated (and I do drink more when I have the CB) far outweighs the extra heat on my back...and it's nice to have the extra cargo space on the longer rides. Overall, I'm happy with it.
I went to Mizzou...I loved Columbia when I lived there!
