i've got no personal experience, but deal with a lot of hoyt shooters i make strings for. the better shooters (maybe what i mean here is the more finicky tuners)get hard yokes, and they don't want serving at the split. if you look at the bow from the back, with the string facing you, you should be able to see which side of the yoke needs twisting by looking at how the string is coming off the cam. personally, when i do it to 1 of my bows, i don't worry about getting it perfect at rest. its more important what the bow is doing at full draw - at least that's what i'm told. i do usually end up putting about 3 twists in the right side as i'm right handed and that's the side that needs twisting because of the cable slide.
