Balance seems fine and in fact RA "appears" fast and even when you move counter-weights to off set this - it still seems fast. So good part of the challenge is its consistent.

I am sure it is mainly polar mis-alignment I am experiencing - my 'internal' issue is I am surprised at how it is manifesting itself.

I think what I must do is babysit it and see how the drift is manifesting itself over 10 - 20 minutes at the eye piece. Normally I set a stop watch - go and watch and episode or two of the West Wing - then when this is over - say 47 minutes - see how much drift and in what components I have experienced - adjust and re-centre - then re-set the timer and go again!

I try and track very close to the meridan (to amplify any apparent error) and would expect the error to vary (decreasing) with altitude. So far I have only tried this on the East - not yet the West.

More experimentation to come!
