I voted Pavlik, cause before his fight with Miranda, I'd have probably gone for Miranda. I think the middleweights will turn up more and more in these polls, cause they tend to be populated with some guys who are fairly short but are really strong. It's where the balance between muscularity over height and reach is at it's peak ratio, if you know what I mean.

The relative power of the heavyweights will tend to rule them out for the most part, but super-punchers like Tyson will always emerge once in a generation.
