There are so many variables involved. Some bars might be perfect for one rider, but torture for another. Saddle height, bar height reach, width, type of handlebar wrap all play a role, along with shape. I like Nitto Noodles and some French Randonneur bars. Nitto Randonneur bars are copies of the French bars but I have'nt tried them; they're not cheap. The VO Randonneur bars are good, but I wish they had a little higher "bump".
Those are my preferences, but I am not saying they would work for you.
I also move my hands around the bar a lot.
