additional length makes the geometry better. Theoretically the arm will track better.
There some stellar 9" arms though, so it's really pretty relative.
I have always wanted to try a linear tracking arm to do away with the geometry/tracking error problems inherent in pivoted arms.
I have seen a lot of excellent reviews for the Terminator linear tracking arm from the UK.
