Is a spinner worth it?

[Mark70]

The spinner makes a gigantic difference in arknoid and other games.  I don't have a spinner on my CP.  For fun I hacked a mouse and made a spinner out of the bearings and axel from a roller blade wheel.  Add in a bolt or two and some large diameter washers and you have a spinner.  After doing that and trying even my bodged togther prototype spinner with no knob and only a bolt head to spin with... it was better than the trackball.

If I could add a spinner where it wasn't a danger to your health playing golden tee, I would do it.  I'm considering doing it when I change my CP art.
