Well, I just realized that I've outgrown my LowePro Slingshot 200, and am looking for a bag that is a bit bigger. Anyone have any suggestions? I currently have a LowePro CompuTrekker Plus (massive) so I'm looking for something a bit smaller for lighter trips. Here's what I'm looking for in a bag: - Backpack (2 straps). Want to be able to take it on long bike trips with out it killing my back / shoulders. - Small to medium in size. - Room to store things other than just camera gear - An all weather cover to protect my gear if it rains - Tripod holder Anyone out there using any such bag? Thanks!
