Both the Tribute and Allegiance should both be a bit faster than the Mighty Mite....especially the Allegiance. The newer Binary Cam system is somewhat more efficient with any of the given Bowtech bow designs. How much faster? I guess that would depend on your setup. The Tribute would probably be somewhere in the neighborhood of 3-8 fps faster than the Mighty Mite while the Allegiance should be a good 10-15 fps faster at the typical IBO specs.

Different feel entirely though in terms of the draw cycle and the shot.
