Without knowing your PAP, it would be difficult to predict with any certainty how this layout would work for you. However, *in general,* pin-under layouts with the pin on or near the centerline tend to yield more even, controllable reactions. The cover on the Ab is versatile, so if you don't like the length you're getting from it, you can always tweak the surface.
Hope this helps.
