I like the Champions a lot. They are wide and flat on the top bending a fairly quick 90 degrees to the lever mounting point. This allows a wider placement for my favorite mirror style. The wide flat tops also accommodate my favorite hand position at that first bend for upright riding style. The shallower the drop the better, and wider is better still.
Another bar that is fairly close in shape with even shallower drops is a Winpista as seen on some late 80s miyatas.
