I'd have to agree with Pinwheel on this one. If the "hybrids" can be made to shoot as quietly as a good single cam, then their other advantages will probably doom the single cam as it now exists. However, twin cams as they now exist, will not. Average hunters are the ones who dominate the market and they are not bow savy to the point where they know much about creep tuning, or cam synchronization. They will make choices based on the obvious, which will be what they hear and feel. A single cam that sits in the closet all but 2 months a year will probably shoot better groups than a similarly used twin cam that has never been tuned. For sure, it will sound better doing it.
