Hi, I'm thinking about why shielded twisted-pair is still twisted? Pair is twisted for controlled distance/impedance (due to twist) and for x-talk reduction. If a pair is already shielded together, it is not necessary to twist them any more. Without twist, it will be equivalent to twin-ax cable, isn't that better?
