Len--ONE turn or two--(I think the Bowtech manual say NO MORE than THREE turns) is OK on the cables.
I tinkered with my Allegiance after changing the cams to attain the correct BH.
The bow came with a slightly shorter BH, the ATA was fine.
We assumed the shorter BH was attributed to the string track in the cams, but a twist here and a twist there and another twist, (twisting the night away) got me what I was looking for.
Both BH & ATA are now dead on spec--the Let-off where I want it to be, gained some speed and the bow shoots like a 'dream'--now I've got to work on "ME".
