Cable management has always been an issue for me. The braided seemed to be the best idea (in my mind) because they generally get tangled less. It's like with headphones when you put them down, next time you pick them up, you have a giant knot in them. SteelSeries actually might have solved that with the Siberia Elites, I have a video coming for that too as well!
It's like a flat, thin cable, maybe that will make its way over to the mice!
