Rob,
The G11 is working very nicely - the pHD RMS value is always below 0.1 and it is often achieving 0.06 (without pec). It seems to be happy with the 10" newt and I've had no issues with motor stalls during slews. I needed 40 lbs worth of counterweights to balance it.
The only thing I don't like is the backlash in the dec axis as it makes centering the object painful and it takes a while for the guiding to settle however once it is guiding I've not had any problems. I will probably have a go at adjusting it some time.
I haven't tried to measure the PE however the curve that Adam posted showed it was quite good (+/-3 I think). This is quite a bit smaller than what I was seeing on the EQ6 however the rate of change was small so it was easily guided out.
