I am not sure how long the Browningis ata or what the brace height is but take a hard look at the APA black mamba extreme. This is a seriously fast bow that is surprisingly easy to draw back and shoot.

I recently shot this bow (60#, 26")and theswitchback xt (70#, 26")through a chronograph with the exact same arrow.Both bows shot 261 fps. But the APA did it with 10 pounds less weight.
