Which is why you want the antenna torque balanced. Then it doesn’t matter what 
direction the antenna is pointed, or where the wind comes from.

Modern software makes it easy enough to do that there is no reason not to do it.

Yes, I guess it depends.  If you have very small elements and a long boom, that 
would certainly make sense.  With large HF arrays, I guess I would try to 
orient the antenna to  lesson torquing around.  At my QTH, the wind 
continuously changes directions, in gusts.

In my experience, head the beam into the wind, like the bow of a boat. All 
elements are then subject to symmetrical loading. At ninety degree angles, 
individual elements sometimes whip around on their own course, and occasionally 
into some sort of mechanical resonance.
