We definitely have different trimming methods. I bet we end up at the same point though. What has always worked for me is to only adjust engine thrust line to correct vertical track. I would think that adjusting the wings to more then 1/2 degree would take away from inverted flight too much. Then again everything is a compromise. The best we can do is get the airplane to do everything reasonably well. If we get lucky it does some things exceptionally well.
