I know we talk about bags a lot. But what about internal bag organization?

Between patch cables, console cables, fiber cleaners, my laser, SFPs, WLAN Pi, WiSpyDBX, a mouse, some spare batteries, a few small tools etc etc, my backpack is slowly turning into a disaster (even with its internal organization). What are you guys using to keep things together, besides velcro straps?

Thinking something like this or this.
