FWIW, I tried the Compass Rando bar in 42mm width. Here is a pic of the bar:

I ended up not liking the up-sweep. The was no place on the flat section of the bar that was truly flat. My wrists were always at an angle. I know that is the idea but it did not work for me. These seem to be a bit more pronounced than the other types of Rando bars I tried. YMMV.
