New kid needs some string
 

I have a PSE Fire-Flite Express compound bow and its string broke.
My Uncle got it used at a pawn shop and the markings on the bow say that,
set draw length is 29
peak weight is 70-80
let off is 60%
cable tune number is 2230
string lo is 3261

The above site says that I need 54.50 string, but I'm not sure where I can get some or if the info is correct. So can any of you lot help me, please?
The cables are fine I just need to replace the string.

You're in the right forum. There are some extremely knowledgeable guys and gals on here and one of them is even a rep for a bowstring manufacturer.

More than likely, you will need to get a string made by a custom dealer. That's a fairly old bow so it may be pretty difficult to find one at a dealer. I would suggest getting in touch with Lancaster Archery. They have several custom string makers both on staff and under contract. They have pretty reasonable prices as well. http://www.lancasterarchery.com/

Just tell them exactly what you have and which draw length module you have installed and then you can discuss which material and twist and such with them.

And just another thought. The cables may look fine but could be dried out and brittle. You don't know how long they've been laying and tension or shooting could cause them the snap. It would be a good idea to replace them also. You can get the entire set (cables and string)
