Overlay the constant operating gain circles with constant available gain circles. Compute the input and output stability circles. Choose a load termination such that it is on an operating gain and in the stable region from the input stability circle. Choose the source termination position such that the distance to the output stability circle is sufficiently far and the available power gain is high. If the stability performance is not suffice, change to accept a lower value in gain and repeat the process such that a compromise can be reached between the gain and the stability.
