Coleridge,
Seems you have a good system that works.
For me, with the Fox Pro, I have had good success by beginning with the Crow & Owl Fight. They respond and I beat them back some, then I switch sounds to a young crow and they generally come in for another round or two. I rotate between these sounds and have called them back in several times.
J.S. Crow & Owl Fight has been my all-time favorite since way back in the 1960's. Also, way back then, Wightman Electronics offered a "Young and Nesting Crow" sound (45 RPM for the record player types) that was dynamite on crows. I used that sound and the crow and owl in the summer months after the crows were old enough to fly about good. They looked like a full-grown crow, but were young and easily called, as was the older birds when they heard the distress sounds of the young. Thanks to Jimmy Carter, those days are gone - when the calling was at it's best.
