Balance generally is pretty good but with a huge filter wheel it can be a bit hard at times. That said I have checked a balance a lot as SB mounts need to balanced really well generally to get best performance.

Paul: sorry, no brilliant ideas from me.
Cheers,

0.02 seems like an idea to me. I might have to give that a shot and see how that pans out. Going higher up to 0.07 gave pour results so I will try lower.

0.01-02 seems like a reasonable place to start. I will trial a bit with the aggression. My PA is at 0 nothing to move in either axis.
See the new log attached loaded into excel, but in winzip as excel files are not allowed here.
