Got a new bag. Thinktank Streetwalker.

Top left to right: 24-70 with hood reversed, 135 with hood reversed, 16-35, cards holders.
Bottom Left to right: flash triggers + remote, 600EX-RT +blower+diffuser+16-35 hood+1.4xIII can fit (not shown), 5D3+85mm.
Everything fits. There is also a small softbox in the top compartment, carry speed strap (CS pro), tons of batteries.
It doesn't have that much room for anything else, but you can squeeze a few stuff in if you want.
The bag is relatively small (what I wanted), and squeeze all the gear I want to take without using one of my larger bags or shoulder bag with all that gear. Doesn't weight much.
I was considering this or the flipside 300, but the flipside compartment dividers felt not so good, and I had to really squeeze stuff in to make them fit. The streetwalker went just right.
