Steve I use a Gamma 6004 6 Point self-centering. I used to see a lot of the Prince Pros that were all distorted and the original Wilson Hammer OS version was bad for that. But most of the time the graphite frame restored to the correct shape when the strings were out. On the Prince aluminum frame you had to restore them before you strung them.
Everyone has the right to be stupid... it's just that some people abuse the privilege...
