Hey guys thank you all for the suggestions and insights. All of you suggested very good quality bags, but may be I was unable to communicate myself fully to some of you (but I am still thankful for all the suggestions). For example I am/was not looking for something like Tamrac expedition 6x - which looks like a very nice sturdy backpack. But I already have one like that to "carry" my gear from one place to another and this type of "open me entirely to access the camera kept at bottom" is exactly what I am running away from. I am looking for a bag which can accommodate just two bodies with two lenses attached to them when I am walking around - on street roads, on the beach, in the forest etc (and only as much extra space for extra cards, battery, filters, and a remote trigger). Just that. When I am outside I rarely use flashes, and I hate to change lenses outside - so I do not carry extra lenses while actually photographing - those stays in my room (hotel or otherwise). And the two bodies are both crop bodies (40D and 50D). I somehow feel uncomfortable with the side bags - not sure why, but I feel restricted somehow in my walking. As some of you mentioned there is no bag that will meet my needs 100%. I need to do a bit of search on the suggestions of buying a trekking backpack and fitting it with padding and separators. I never thought about that. The Kata 3in1 also looks promising. So let me do some more search. Thank you again to all of you (and those who might chime in after this post).
