I'm another that uses a string with two big leather cups. I have a running knot in one end and when I have the limbs trimmed, but no nocks in, I adjust the string to close to what I want as a string length. I have woodworker's holes in my bench and set two pegs in them to brace the bow against and put the cups on the ends of the limbs. I'm then able to string it, put it on the tiller board and, if all looks good, get a draw weight. At that point I can decide whether to further grind the limb sides, maybe decide whether I want the nocks a bit further down the limbs to increase weight, or whatever. It works well for me.
