I would keep the layer height constant.
The lines are not circular. You can have narrow lines and wide lines with the same height. The height is controlled by the space between the nozzle and layer below. The width is controlled by the amount of material you extrude.

This shows what happens with two different extrusion rates at the same layer height.
