That's one of the things that's pretty particular for each rider. But I'm sure there is a windscreen and/or Madstad that will work for any of them if the stock one isn't perfect. On my DL1000, the PO had a stock screen with a Madstad and Laminar Lip. It was set to the highest setting. Even at highway speeds it was virtually silent and wind free. It felt like riding a Goldwing - and I hated it. I don't like looking through a windscreen and prefer at least some wind at head level. But just using the stock screen and Madstad and lowering it made it perfect for me. I think for touring, the main focus is getting the wind blast off your chest and avoiding buffeting to prevent fatigue.
