The Bowtech dual cams definitely have a stiffer draw cycle though both are on the far end of the draw cycle spectrum. The Spiral cam with the draw stop does have a solid wall at full draw and feels roughly equivalent to the Bowtech duallys. The difference overall though is in the speed you are obtaining with any given brace height. The Supertec requires a 6 inch brace height to get that 330 fps + IBO speed rating. The Bowtech Patriot DC has a 7 5/8 inch brace height and is rated between over 330 fps as well.
