not to highjack, but in terms of speed for binary vs. solo cam, i've found, or think i've found, that the amount of degrees of parallel of the limbs also can have a noticeable effect on speed when set at the same draw weight. using my chrono i've found that my diamond marquis ( single cam) can keep up with my shadowcat. I did find that the bowtech brigadier was slower than either the diamond or the shadowcat.
just my observation.
