i have a friend who has a martin jaguar. he thinks it is a 97 model. he wants to get a string and cables for it but don't know the length. could anyone tell us what type of cams he has on the bow. the cams have a stamp on them that says "us+". please let us know what they are. i don't want to "just measure" the old ones because i am not sure they are correct. the bow string is rubbing on the "v" in the limbs.
