On the first drilling depending on your release the both in therory should go a good distance down the lane and have a strong motion towards the pins if the lanes are drier on the backends it will show you a skid flip reation. On the second drilling if you place the pin about 1 1/2 inches off your val and about 4 - 4 1/4 inches for your PAP with the mass bias located near the 85-90 degree mark (near thumb,will produce length with a good snap once in the dry. This layout works well with people who have med to high ball speed and revs. Hope this helps.
