CLB made a very fancy and innovative high end set of centerpulls. The pivots are angled so the brakes are self energizing. The center "cable" is a solid wire integrated with the springs. I have a set but I haven't used them yet. Rare and hard to find.
I think that you will find that the Campagnolo Delta, Wienmann, Modolo aero type are poorly suited for a sports tourer in term of length and clearance, give poor performance and are a headache to set up.
I would also consider an ordinary set of Wienmanns or Mafacs with good shoes. Mafac Tigers baby- now why the heck did they stop making that brake with beefier calipers and fancy shoe adjustability?
