Not familure with that bow, but that is a lot of ground to cover(2 to 3inches)with one bow. Dont change the string, that will screw up your timing. You can look it up and see how to drop the draw lenght as well, you can twist the string up a little, and loosen the cable a little depending. You will most likely need a press to do so. Id suggest having a pro shop look at it. As for whether you should keep it or go with another,,,, all depends on how it fits you. Id set it up for you and shot it some and decide from there. Im not a brand specific type person, I feel fit and feel is more important.
