I have similar specs to you and of the 4 x-Factors that I have had the one that I like best and has proved to be the most versatile on a variety of conditions is drill pin above fingers 5.75" to PAP and RAD in the strong position.
I bowl on wood, 44' medium load tree pattern, with strong backends.
I have a small amount of axis tilt which gets everything I roll into a roll a bit sooner than average, so you may want to go a touch stronger say 5" pin to PAP.
Even at this Pin to PAP distance I still get nearly as much flare as the strongest drilled I have had which was 3.75" to PAP MB strong, only about 1/2" flare difference.
