RE: High Country...inconsistent???
I had 2 High Country Royal Hunters(great smooth bows) with the hatchet cams and no problems. But I also had a High Country Top Flite that acted the same way as you describe. At first I attributed it to string stretch, fast flight strings would stretch, but it simply would jump out of tune as the timing changed. Sold it to a guy and he had the same problem. He got rid of it too.
