The answer is there's no simple answer. From the perspective of the
rotator, you'd want to point the antenna in a direction that results
in minimum rotating moment. Both the boom and the elements of a yagi
antenna have wind drag, and therefore both contribute to rotational
moment. If the boom is asymmetrically mounted (liek a KT-34XA), it can 
have substantial moment of it's own. To determine the direction
that gives you minimum moment, you need to calculate the drag as a function
of angle for each of the elements and the boom, and add u all the 
contributions. Such calculations are done in the W6QHS book I keep
plugging. Bottom line is it's different for each different antenna.
