I had an 05 liberty it was one of the best shooting bows that I've owned until I dropped it 22ft out of a tree,70# was like pulling 60# if its an 06 it's a really goodbow which was when diamond took over the single cam bows that bowtech hadin 06 they changed the cam a little on the 06 I shot it and it was smoother than the 05 and a little quieter,they were both shooters though good solid bow.........Ted
