Looking for a bag

Hey guys, I'm looking for a new bag. I currently have a vertex 100 and it's a huge bag but it fits my gear. I am looking to downsize but still fit my gear in.

I currently have:

•sigma 120-300
•canon 100L
•canon 7d
•sigma 50mm
•2x teleconverter (sigma)
•canon 430ex ii

Anyone got any suggestions?

Oh! with the vertex I ALWAYS get caught at secruity, looking for something less conspicuous

I just converted over to Domke shoulder bags. My F-1X holds all my gear with room to spare and their US Post Office shoulder pad works even better than advertised. I also added the 720-230 insert instead of the one that comes with the bag. Here's a quick shot of it loaded.

do you want a shoulder bag or backpack?

Either something that doesn't stand out.
