I just read an aticle and they say it is ibo ratings. But I see alot of people nocking it down when they haven't even shot it I guess if its not A bowtech or a matthews it just can't be any good. And when poeple start by saying this has been beaten to death well go back in the pages of this forum the whole thing is nothing be repeats and repeats and repeats and repeats repeats and repeats who cares then don't reply move on. sorry just venting and saying don't knock it till you've tried it I know a few people who shoot bows with under 7" brace height and have know problems shooting.
