Likewise a machined/cast riser at any price break, so I do not understand how any line or reference point on a riser can be used accurately as a guide for setting up the limbs especially the tips to be straight. In it's basic form all the riser is the stiff bit of material that holds two springs together and as long as the limb tips are pointing in the same direction and the string runs down the centre of each, the bow will be accurate as the string touches no other part of the bow and the arrow touches the string and the rest/button. I have seen too many bows where the string runs down the centre of the handle and most of the limb including most of the string grove, yet the tips are out of line, which at best means the bow is not as accurate as it should be and worst puts a permanent twist in both or one of the limbs.
