I'm 6'3" and I've been touring with an MRA Vario screen and Aztec spacers. The combination works well for me. There's still significant noise with the screen in the highest position and the wing fully extended, but I find that position plenty comfortable on long rides. I think the MRA Vario is the best compromise between looks and performance. It's stylish and offers good protection without looking like you've mounted a barn door on the MTS!
However, at the moment, I'm testing an MRA Sport screen with Aztec spacers. You can definitely tell there's much less noise using a small sport screen, but it clearly offers less protection. I need to do some extended freeway or open road riding to see what it's like touring with a sport screen, before I decided if it's better for me than the MRA Vario.
Another option I'm investigating is the MRA X-Screen. It's a larger wing that's more adjustable than the wing on the MRA Vario. I'm going to find out if the X-Screen will bolt into the same holes as the wing on the Vario. If it does, I'll swap out the Vario wing for the X-Screen.
