Very nice little minicomparison of the three bows in question. I think you hit upon the key differences between each model. The Black Ice does have an exceptionally smooth drawing cam for the speed it puts out. I, too, am a little surprised at only a 10 fps speed difference but then again the Allegiance did have the smooth mods installed.

I do not think you can go wrong with either of those two bows. They are both excellent shooters!
