The "luring the Death Star into a trap" rationale works except for one small quibble: the Death Star plans had NOT been analyzed yet. Leia didn't know whether or not there was a weakness in the DS that they could exploit. Remember this?

Dramatically and cinematically, it works. But it makes no logical sense whatsoever.

I disagree. Given that the Death Star was about to be the ULTIMATE POWER IN THE UNIVERSE and give the Empire unlimited authority through unimaginable fear, I think the Rebellion was going to have to fight it anyway, convienient weakness or not.

If they didn't, it was over for the Rebellion anyways.
