I don't think singles are better than duals. IMO, they generally draw a bit harder, peaking later in the draw, although Bowtech's Freedom cam and the Mathews HP are exceptions. The singles are generally a bit quieter than duals and most hybrids. They are more expensive due to increased popularity (due to lots of advertising in magazines and hunting programs), plus most single cam manufacturers must pay a royalty to NAAG, I think. I prefer duals in general, although I have had a few lately that lend credence to Mathews' claim of synch problems, especially with vertical grouping, creep tuning, and 80% letoff modules. Then again, the last single I had seemed to have semi-serious nock travel issues, and was difficult to tune with broadheads. The hybrids I now have (Dartons) shoot very well for me, tuned broadheads very easily, and seem to stay in tune well. The Tundra is very quiet as well, basically equal in noise to most singles I have shot. I would agree with some who mention the noise level of Dartons that the 2003 Rampage I have with Express cams could be quieter, although it isn't really all that bad, especially compared to the pre-Sims bows I used to shoot.
