RE: allegiance/tribute
I shot both and chose the Allegiance. I like a little more ATA length. Once a good stabilzer was put on these two, neither of them exibited much handshock at all IMO. I also liked the added speed of the Allegiance. Though I'm not a speed freak, I figure if I can get more speed for "free", why not.
Either way, you can't go wrong with either of them. Both are plenty accurate, fast and quiet.
