Gotta agree with Fletcher on this one, unfortunately some people are just afraid to say "I don't know". If the actual string length was 58" then the bow's probably fine, but I'd still give it a good looking over. Either way, its too short. Buying strings can be very confusing, some are sold by actual length, and some by AMO length, which can differ by as much as 4". If they've got any business ethics/morals at all, they should refund your money, but the way things have gone so far...who knows? Either way, they wouldn't get any more of my money. Like others have said here, I'd give one of the sponsors here a call, whether it's one of the custom builders or 3Rivers and make sure it's right and more importantly... SAFE.
