Dan, I wish I could help, but unfortunately I know nothing about any of these bags, But I do have a couple things you may want to consider:


1. You have a body, 4 lenses, a laptop---andI assume a few accessories----do you plan to carry all of it in the desired bag? If so, This could get very difficult anduncomfortablewith one (1)shoulder strap.


2. Do you do a lot of walking/hiking or city touring with your gear? If so, you may want to consider some level of rain-proofing and a place to carry a camel pack or water bottle


I purchased and used the Lowepro 300 Slingshot AW--A very Nice Bag, did everything I wanted, But.....I failed to heed Bryan's warning and discovered that this one strapbag is very heavy and uncomfortable when fully loaded, I should have gone with a "back pack style instead"---That's on the wish list now.


Good Luck on your search--


Bob
