If it were picking the smallest PD component, then it would use Self-Defense Cannon, which is smaller than the PD Beam. If someone figures out what's determining the choice, let me know. I'm sure there's a way to do it though, and will figure it out if no one does first.

As for planetary shield platforms, one nice thing about the really tough troops is that they tend to get destroyed after weapon platforms. If you made a really strong shield plaform with phased shield component, though, it might just be the Last thing to go before population and facilities, but would not protect weaker units, such as platforms with weapons, units based at the planet, infantry, etc.
