I think the responses by others, especially Jeff's, really nailed it. Even though certain aspects of Hoyt's Cam.5 are not necessarily better, or even as good as the CPS, Hoyt did several important things.

1. A major player in hunting, 3D, and target bows decided to make ALL of their lineup with Cam.5.

2. They advertised very effectively, if perhaps overstating the virtues of their system somewhat. (Sound familiar?)

3. As stated earlier, they produced a hybrid that was smooth and quiet to shoot. Darton never seemed to focus on recoil/noise reduction as a design element for the CPS. Hoyt did.

Some other hybrids, particularly the Newberry, look like they have designed a hybrid system to be optimized in many respects. The Champion Scorpion looks pretty good too. If I hadn't just gotten a very nice 2 cam (wheel) bow that I like very much, I would probably take a good look at some of these new bows.
