OM-D - which bag?

I've been using the Blackstone Bags Urban Quiver. Only just came back from a two-week trip overseas recently, carrying that almost every time I went out.

What's so great about it is that it doesn't really scream "CAMERA BAG," has no markings, has a very flexible spacing "system" due to the fact that it's designed to be square, and is fairly secure as the zippers will be facing your back when you have it on. Of course, it's not designed for speed...but its slender build makes it pretty easy to squeeze between, say, food court tables and whatever else.

Here's how I spaced mine:

Blackstone Bags Urban Quiver.

What I got in there:

• Olympus FL-600R and kit flash
• BlackRapid RS-7
• Voigtlander Nokton 17.5mm f/0.95
• Olympus M.Zuiko Digital ED 12-50mm f/3.5-6.3
• Olympus OM-D E-M5 with HLD-6 horizontal grip attached
• Olympus Zuiko Digital ED 50mm f/2 Macro with Olympus MMF-2 Adapter
• Olympus HLD-6 vertical grip
• Off-brand flash plastic flash diffuser
• Rocket blower with 3x lens pens and cleaning cloth
• Foldable flash diffuser/bounce card/correction gel in side pocket
• Thinktank Pee Wee PPR card holder

The bag only feels heavy because of the Voigtlander.
