There was an interesting post by Roland Christen recently on guide scopes.
Basically the guide scope should be mounted on widely spaced rings on the OTA not the OTA's mounting cradle. So that the guide scope floats freely with the OTA.
That makes sense that way if the OTA flexes slightly it will take the guide scope with it rather than differently which causes problems.
So a finder scope mounted to the OTA rather than the OTAs rings or a top dovetail may work a bit better.
