Totally opposite indeed, as I still use DST for the roughly-sawn faces and superglue for the second pass.
Well, the thing is that I can't find here DST thin enough, the one I use is like 0.5mm thick... so the veneer gets 0.5mm separated from the surface, plus the stupid elasticity it has, makes the veneer moving up and down, even left to right while passing the router. The movement is minimal, but I could check myself just pushing with the fingers. Superglue+tape keeps the veneer completely fixed to the surface, which gives me a much more consistent thickness.
