Thanks guys,
I've thought about the bike, but that wont be for a number of years... Got to many prodgects to do in the mean time.
This prodgect was done on the cheap, so all remnant peices and the 1.1 oz was the best I had for the purpose. The 1.1 is covered pretty well from abrasion though. I leave it far away from my backpacks for that reason. Realistically oxford and packcloth would be a better choice.
bmsclaughlin... why not make a panier or at least the lap top cover. Think a taco padded with a foam sleeping roll from malwart. If you have a sewing machine then try it. At worst you waste 30 bucks. I'm not shure how you would fit that into a pannier though. It would have to be strapped (with the straps sewn in the perfect locations) on top the rack.
Anyway... Now I have no excuses not to commute,
Scott
