for a destroyer...baldyhunter!
There's no such thing. Your bow is either tuned the best it can be or it isn't....the end. Not knocking crackers or any of the other guys out there but they're not going to get more out of a bow than the manufacturer can unless they cut a few corners like short string bows, switch the strand counts on strings, etc. . I'm not saying they do this, but if a bow was capable of shooting 15 fps over it's IBO from the factory don't you think the companies would have it rated at 370 instead of 355 considering how big the speed game is again???honest question: what is a "supertune"? Never hear of such a thing...
