I just traded in my 06 Tribute for a new Guardian last night. I shot the all the 07 Bowtechs and decided on the Guardian. It is a little quiter out of the box and more forgiving. I was shooting half dollar groups after 10 shots at 20 yards.

Shoot them all that is the best advice. I had all three there and shot them back to back to back. You will isntantly discover why some prefer the Tribute or Allegiance as they all have different feels.
