Oh my god, Doug! I'm laughing so hard at the pic! Maybe because it looks like you're trying to scare this OP! Funny. 2 months ago at an REI in S. CA, they had one of their bigger versions on serious discount (not at another store tho, strange). Sorry, but there's no way that the design was well thought out. I took one of their racks and attempted to figure out how the pannier would stay on the rack. The employee didn't like that I was questioning it and gave me serious attitude. Don't care - I'm not a stupid chick and I ain't gonna buy crap. So do what I did (with other panniers as well, if you can) and see what you think works. Personally, I think the bungee pull with S holder works best. I did 5 tours with Lone Peak panniers and highly recommend them (if they haven't changed the material). They're made in the U.S. still, but now cost a bundle. For waterproofing, do 2 simple things: line the sectionals which will contain your clothing with plastic bags, and buy a can of waterproof spray for boots and spray the panniers. And remember: it's usually a choice to ride 2 days in the rain!!
