I *think* that should be read to mean set the riser's limb bolts to equal, ie the same number of turns in or out. So zero on the riser, would produce the limb's natural tiller.A couple of coaches keep telling me that modern bows should be set to zero tiller. I have assumed they are simply mistaken. From what I see, even top line bows, shot with med. release, will have some positive tiller, unless maybe for a really low grip. Am I generally correct? I don't want to pass on incorrect information and from what you say, a bit of positive tiller would be the norm.
That would be my starting point with a new set up anyway. and usually it's minor tweaks from there.
