I have the touratech. It's been on the bike for nearly seven years of abuse, taking lots of hits. It serves as maximum protection, a jack point, has optimal air flow, allows for vent tube to stick thru, self drains, removes in seconds, can store tools and a toolbox, and costs a small fortune.
I bought it cause it was the only one available at the time. I would, in fact, buy it again.
