Why do You keep repeating Yourself as if somebody was arguing this point or claiming to not understand it?
The only possible "debate" here is which has more influence, thrust friction reduction or rod angularity early in the power stroke, by flipping the OE offset. Again, who cares?
Nobody, not You, not Dan, not Me, are going to prove anything talking about the theories and effects. The ability to test and prove the degree of effect is very difficult.
A lab at MIT might build a test engine to quantify changes and dynamic impacts throughout the cycles, wanna pay for the study? Save it,..................................
The general consensus here is, don't bother with the long rod build unless You're planning on pushing for racing RPM's, which it sounds like the OP is not.
Now go have a beer & relax!!!
