I coil mine over-under and simply store them that way in my gear bag, caps attached and protected by DPA UA0896 windscreens. Unless you're abusing them, they shouldn't prove any more fragile than regular mic cables. Also, make sure you don't pull the caps in/out of shockmounts, mount bars, etc. by the cables themselves - better off using the collette connector or cap so you don't stress the cable.
