Hi Greg,
I use a SX-AO (not the LF version) with my SBIG ST-8300 with no problems, but only at 1650mm FL with a GSO-RC8 on an EQ6pro. I guess at the FL I'm using I don't really see the benefits of beating the seeing. What it does do though is allow me to do longer exposures than I could without it and still get round stars. I've gone as long as 1 hour subs with round stars - not bad eh!!
Guiding really becomes easier using AO, becomes hard when you have to go back to using just a guide cam.
