couldn't tell a difference so may as well get the faster one IMO.
Atlas, like Matt/PA, I have the privilege of shooting both any day I want to; for the reason I quoted above, I invariably find myself picking up the Allegiance just about every time. I wished I had access to an Equalizer to help you out, but I can tell you I am EXTREMELY happy with my Allegiance.
And ... unlike Matt -- as most people know -- I recently switched from shooting Mathews. As I still own a couple, I get to shoot my new BowTechs heads up against them any time I wish, and I can tell you: my BowTechs are quieter than the newest, top-of-the-line offering Mathews is currently touting. I don't think you've got to worry about noise issues when contemplating BowTech as your hunting bow of choice.
