i'm thinking magnetic with map holder. expandable would be nice, but i would like to have an inside dimension of around 9x12x3, to allow me to put in A-size papers/reports, wallet, sunglasses, cell phone, office keys, hearing protector bag, etc.. anyone out there tried the [URL]http://www.k-drive.com/7Nomad%20Tankbag.htm[/URL] or knows where to try one in the bay area? i'm also looking at some additional luggage for a round trip to seattle in july. givi is nice, but most of the time i won't need that much storage, and am tempted to just bungee on a soft carry-on suitcase ... thanks in advance for advice on this, ferenc
