It would be nice to know how others have tweaked this nice little mount to make it even better.
From my side, the one tweak I did and that I can highly recommend is to replace that very short Vixen Clamp with something a lot better.
My issue with this clamp is that it is simply to short to properly grab the Vixen Style foot that comes with the Ascar acl200.
So what I did was to order a clamp that is suitable for both Vixen and Arca Suisse dovetails from Teleskop Express in Germany.
Then I 3D printed a small adapter to fit the screw holes of the custom clamp to the holes of the Skywatcher GTi.
Here's a closeup of the adapter plate and the clamp:

and here the fully mounted scope:

and here's the STL in case anyone is interested:
Skywatcher GTi Adapter v2.stl
