70lb Liberty at 28" draw. There was a little debate at work over which arrow would be the "correct" one for that bow. I believe based on my experience that the 250s while weak in comparison and weak based off of a program like On Target 2... will shoot every bit as good out of the bow as the 350s. They both paper tune and group the same from my experience. People tell me Im wrong and have to go with the 350(even Carbon Express said the 250s were too weak and wouldnt shoot them out of a 60lb bow!) but I dont believe the setup is that sensative. Plus how on earth can a guy get an arrow down to 350 grn shooting something as heavy as the 350?... you cant from what Ive seen. What do you all think?
