Sometimes I plate solve before I start or after a meridian flip to get the scope pointing in the right place.
During an imaging run I just dither between exposures. I believe (from memory) you can't dither and astrometric resync. It has to be one or the other unless you use ACP or something like that.
I guess your flex is giving you all the dithering you need, but I think it would be better overall if you could somehow stop that drift and start to dither. Perhaps an OAG or rearrange the guide scope setup?
