Anymore people want a single cam.They say they are not as easy to knock out of tune and such.If one kind is selling more then the other then the price will be affected.If they made too many of one and havent sold enough then they will drop the price accirdingly to get them to sell faster.Personally I have always shot a dual cam bow.I would rathr shoot a dual cam then a single cam any day of the week.When I am hunting for a new bow the first thing I look for is dula cams and nothing else.I guess it is just a amatter of prefference.
