It feels a bit different, so it takes a bit to get comfortable and to get YOUR right position. Try out what happens if you change the "spearing point" of the arm. Put it more up and down (y-axis) and more in and out (x-axis). The point you can comfortably hold the arm without loosing balance is your right point. And it's rather out and rather a bit down than closer to the mid line or to the surface.
