It seems like the line of the arrow impact points, from shorter to longer distances, is pretty close to vertical. It might actually hit a little more to the right at longer distances - although the nock is better in line with the close shots, but thetip is angled off to the right maybe four or five inches from a point directly ahead of the nock. It looks like the rest is already about as far to the right as it can go; as the sight is also about slid to the right just about all the way. Is it possible the too stiff an arrow could cause this, or should I look at a quicker spin to the fletching?
