With TPoint and ProTrack the fork flexure will simply go away. The requisite term (FO) is already in the basic repertoire of terms that the default model includes. Bear in mind that GEMs also flex, but differently: in their case it's from the sagging of the cantilevered declination axis (TPoint term DAF).
The elimination of meridian flip is an enormous advantage. And quite apart from uninterrupted exposures across the meridian, the fact that a much smaller range of mechanical declination will be used makes modelling easier. And no counterweights. GEMs are
nasty!
