Maybe I can help you. As a Martin staff shooter and FireCat owner I know a little bit about them.
Have you ever heard of Stone Mountain Dakota strings? This is an aftermarket string and what's on the FireCat, Warthog, and a few other pro series bows.
Looking in a catalog, if the bow is advertised with Double Helix ELITE strings then it's Stone Mountain. Double Helix is Martin's in-house strings.
So what I'm saying is that, if your bow is anything like mine, you should not have to change the string. I use a 5/16" Meta peep and mine draw straight back with no rotation whatsoever. So save your money for the next set when you need them.
I hope this has been helpful.
