No regrets on my Tribute purchase. Shot my dad's XT and I prefer the Tribute - it is also a
faster bow. With the addition of a STS (which is basically built into a Matthews)
I didn't notice much if any difference in noise and vibration.

Some people like lighter bows, I like medium weight. While the Tribute is clearly a little heavier
than the Drenalin, the 07 Allegiance is a lot closer in weight to the Drenalin.
