The endless loop Boo made string has 105 shots on it. Started off 3/4" above highest brace line. Its stretched 5/8" but still above line no twisting yet. If it will stretch to lower line great, if it goes below lower line i will twist it. This one is showing early signs of wear. Not from rail but from trigger claws and rope cocking hooks. You just have to understand that it has 105 shots already and its hard to judge wear as to when it will need changed out. I know that without any doubt it will go at least the 300 mark. This string isn't stetching like the Flemish one did. That i believe is the reason fer the signs of early wear. This in no way reflects on craftsmanship of this quality string.
