Between the Revolution and the Omega the choice is easy, buy an Omega. I don't have a bias against Knight (I own 3 of em) but I don't like the Revolution. Now Omega vs. a Knight Disc Extreme I'd say go with the Disc Extreme but I am biased there, I own 2 . I also have an Omega and it's a fine rifle and actually better than the Disc Extreme but I got one of the first Extremes and have been hunting with it for almost 4 years. It's a sentimental favorite.
