Bowtech doesn't cut their quality with the Diamond line. I wish I could get a little more speed but I don't really need it.My Black Iceholds well for me at 5'8" tall. I would get the Marquis if I were taller and had longer arms because it is faster than my Black Ice but all of their bows shoot accurately with very little to no hand shock at all and talk about quiet! I put a string suppressor on mine and I cannot hear a thing. If I were you though, you might want to check out the Allegiance. That bow is amazing and it's specs fall right in between the Marquis and the Black Ice for AtoA legnth and weight but it's faster than both of them! Not to mention the beautiful craftsmanship and quality on top of it all. I don't think that I could be more pleased with another company.
