I shoot a Mathews Drenalin. Very smooth draw. Shot bows from Bowtech, Hoyt, PSE and Bear when I was shopping for a new bow in '07 or early '08. None were as smooth as the Drenalin. My brother has a Z7. I shot it and it is not as smooth of draw as my bow. I have not shot any of the newer Hoyt, Bowtech, PSE, or others (2009's or 2010's) so I can't comment on those. IMO, of course.
