If you get on Martin's website and click on Tech Info you can fish around and get this info, but you need to know what cam is on the bows. I did a little looking and here's what I came up with.
The Irion (2005-M83) with the DynaCam single cam calls for a shooting string 86.5" long and a Split string (cable) of 35.25. If the bow has the Tru Arc cam then the string is 48.25", split (cable) 35.25" and the control cable is 39.25" long.
If you don't know which cam then click on catalog and go to the appropriate year and see if you can match it up.
I couldn't access 2008 for the Jaguar so I used 2007 and came up with 87.5" for the string and 35.75" for the cable. This is if the bow has the Dynacam on it.
Hope this helps some.
