then understanding lag loading is the key to the secret...
Let the manner in which you establish lag pressure be the determinant of your right elbow/forearm position....
Once you have found the most efficient alignment for you right elbow/forearm at lag pressure loading.... then make sure that it is in a sensible position at all other sections of the swing...so you have less compensations to make.
If you do this then you find that pitch is most naturally suited to swingers who drag load and have sequenced release...
punch is most naturally to drive load and simultaneous release.
So start with your loading procedure and fit your right forearm to that...
