Starting the spin with left rudder seems to be the best.
With our normal engine rotating direction, theoretical, I expect some nose down reaction as result of stopping spin rotation of the plane that was started by that left rudder and that seems to be a profit.
The amount of “nose down” depends on gyroscopic forces of engine and propeller, so RPM (and a lot of other data). Maybe it isn’t much but it is interesting to observe if there is any difference.

Cees...
