I hunt with the Barnett Demon compound, may I ask what you did not like about the Barnett? I have had two Barnetts so far, and I like them. No rail greese needed on mine, and both of mine are takedown models, for easy packing. What turned you off to Barnett?
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
