Oh one last piece of fodder for you all. A lot of people seem to think that Ortlieb is the pinnacle of pannier engineering, especially considering their price. I realize that they have a great rep and I am absolutely not bashing them. To the contrary they are in my consideration as well!

However, as a counter argument, a lot of folks have long considered Robert Beckman to be the best pannier's on the market along with a similar design from Bruce Gordon. Both are non water-proof, full zipper, lots of load stablilization straps type panniers. I was actually thinking that the LPs would be a sort of poor mans version of the Robert Beckmans. Though those use a much more complicated attachment system.

Check them out if you havent yet and let me know what yall think.
