I have both dual cam and single cam bows. The single is as accurate for me, provided I don't "relax". The dual is more consistently accurate. I can shoot equally good scores at 3D with the single, but I have to be on. The dual helps me through the little lapses, to a degree. There are definitely more tuning options with dual cams. All things being equal, the dual cam bows are generally faster and smoother drawing. They can also be made nearly as quiet, certainly quiet enough for hunting.
