I have not actually shot one of these bows, but I did draw a few at the Harrisburg show last year. They are smooth drawing, with a good, positive stop. If I am not mistaken, Len posted something about the cam after it first cam out. It is the same cam that was on last year' s Prolines when they were still part of Darton, and on the Darton Storm, I believe. It looks exactly like the same cam, and I had the Proline brochure with the description. It is the same as far as I can tell. If I remeber correctly, Len said the level nock travel was not really quite true. I don' t remember anything else.
This is definitely not the CPS system.
I did own a Darton/Proline Mountain 2000 that had the CPS 2 system. The riser had the nicest grip that I ever shot. The bow was tack-driving accurate. It was not blazing fast, but this Post Feed cam isn' t either. The only reason I sold the bow is the noise and vibration factor. I had Limb Savers, string leeches, NV system on the bow, and even put silicone in and around the limb pockets. It still was not a real quiet bow with lighter arrows.
I know this does not really give you all the information you were looking for, but it didn' t seem like you were getting much at all there for a while.
