The defense of Star Trek is so focused on the "frequency" of a beam... in fact, most of this is irrelevant. The weapons in Star Wars aren't frequency based, so you'd have to block them completely. Read more on StarDestroyer.Net - they have a good article on it. Besides, the Borg would be destroyed easily enough.. Star Destroyers, Super Star Destroyers, Death Star... the Empire has conquered the galaxy while the Borg haven't done much at all. The fan fic of SWvsST at SD.Net addresses many concerns. I'm not saying that SW wins outright.. but if it were just open-combat, Star Wars would win on shear numbers and firepower.
