Do you know what string material they are using? Reason I asked is Bcy B-50 stretches a lot. B-55 stretches about the same. Dynaflite 97 stretches less. The point I am making is each one made at the same length is going to be a different length on the bow. Changing the brace height. So depending on the string material it's going to change the out come.
The October Mountain string was supposed to be B50 and the Stone Mountain string package is marked D97.
