I finally got to see "What We Leave Behind", and found my all-time favorite space battle scene there. Amidst all the recycling of earlier DS9 and movie footage, there's this touching little shot where a lone Miranda swerves left and right, desperately trying to shed two dozen Breen ships from her tail - until the pursuers all make a 180 and head towards Cardassia. I truly felt for the skipper of that little ship!
In all, a better episode than I expected from all the reports on the net...
