A 1st Class filter reflector alone does not guarantee a perfect shading system. Much will depend on the hardware system. The barrel or tube to which the reflector is mounted needs to be of high enough quality not to flex. A low quality Aluminium or steel tube at 2m to 3m wide can flex up to 5mm or 6mm.
The distortion this can cause to the 'flatness' of the filter having disastrous affects on both the appearance of and the visibility through the reflector. Our tubes are precision made and machined in Switzerland guaranteeing the absolute minimum amount of deflection.
