any possibility to maintain a heading using the moving map while in the clouds to prevent the start of a spiral dive?

And as you slow down in strong wave you can start flying sideways/backwards and the moving map or fake instrument it is driving "topples". If you want to rely on instruments, they need to be real inertial instrument (and lots of training/practice) in an environment like that.

The near-VNE speed that Ramy described is the eater of gliders in this scenario in strong Wave.
