09' Moab cam/string- cable question

[racknspur]

I just replaced a set of limbs and after playing around w/the shims on the bottom cam the string is still rubbing against the cam as it rolls over and just befor it settles into the mod. groove. At this point I think it has little to do w/the spacing of the cam as it is properly spaced. It seems that the amount of torque placed on the rigging from the roller guard may be the culprit. After twisting/untwisting the yolk a bit to ajust the idler, it is better but still slightly rubbing. Is the idler lean that critical, and should I keep going in the same direction till it dtops rubbing all together?

Anyone? No one?

I like the idea that the idler and the cam should line up perfectly but is it critical? Probably not critical to have it 'perfect'. Critical would be not putting too much twist into the limb to correct other problems, possibly causing limb failure. If they're lined up well and if the string isn't wearing bad and the bow is shooting/tuning well then I would leave it alone.
