You are right about the CPS system that Darton employs James-d. Not many guys around here are shooting Darton. Not sure why. The adjustibility of the bow is first rate. I was able to tweak mine about an 1/8" at a time until the draw length was perfect. Dead nuts perfect. The best part though are the tuning marks they use on the cam and the wheel. Adjust the string so it lines lines between the marks and thats it. With a quick visual you instantly know if the cams are rolling over in sync. That' s awesome. They also do not use a really long string like on most single cam designs. The thing stays in tune with minimal string stretch. I had a Mathews (no slam here guys) and the darn thing changed all the time. I was constantly messing with it to keep it in tune.
