Dallas Kossacks, how should I vote?

I used to be a fan of Dallas Mayor Laura Miller.  Lately I haven't been so sure.  On November 8, I will be headed to the polls for the first time ever, and will vote against the anti-gay marriage amendment and on a variety of other measures.  However, I'm as yet undecided about the Dallas strong mayor proposal.  

After the Ray Hunt issue, I'm seriously questioning Mayor Miller's sanity (his deal really isn't that extreme, but her response sure was), as I have been since the Terrell Bolton fiasco last year.  She simply cannot deal with people, and seems to take a perverse pleasure in pissing people off.  I support having a modern form of government in Dallas, the City Council doesn't work in the 14-1 setup.  Period.  I want things to change, but I don't want to concentrate power in the hands of someone like Mrs. Miller.  In short, I'm torn on the issue: should I vote for a strong mayor, or against the lady who would benefit from that proposal?
