Diamond is slightly faster, 320 for Mmmm and 324 for the Marquis.
And just as a side note to that statement......I haven't seen a Mathews shoot it's advertised IBO speed yet. I will admit my dealings w/ them have been fairly limited, but our chrono don't lie. It doesn't care what bow you shoot....I haven't seen one yet....
Hey, what do I care anyway.......I'm not "sponsored" by ANY bow company, so what the??? I'm out.....later dudes.
