I still run the Bell Laps on my go fast cross bike, which is versatile enough that I felt like the new touring bike should be optimized more for rough stuff/hauling when the previous one was my do everything bike. Plus, the uprights allow me to make much better use of the Bruce Gordon front rack. My thumbs and wrists hated all upright bars until now but I've been liking this ergonomic setup a lot.

The one assumption that drops/moustache/butterfly bars all make is that long distance comfort is found with multiple hand positions, even if it should happen that no single position is particularly good. I personally find the latter part especially to the case with moustache bars. Running 20-50 degree swept uprights with Ergons is more about having one completely perfect position instead of a bunch of compromises and I am liking it thus far (with bar ends of course as an insurance policy
