Len,
IfI don't have a tuning machine, what do I look for to get the lean correct?
I have had lean issues w/ a Switchback and the Trykon I still have. Both tuned very well w/ ata the same on both sides. Was this a fluke?
I understand what gibblet is saying about the cables pulling unevenly during the draw.
On both bows, the top cam/idler are tilted in slightly at rest. At this position, ata is even. I checked the best I could at full draw that the idler was vertical.
