I cant comment since I have not tested 30T/70R or 30R/70T.
I just used readily available 50T/50R and its 5 moons even with #13 welding filter is bright enough. Its much better than using cheap microscope slides that vary from batch to batch. Others with more experience might have an opinion to what is the best.
I tried opening a dialogue with the factory however the language barrier is huge when it comes to the finer technical specifications of their products. They can apply filters to the beam splitters however I had difficulty conveying the importance of eye protection and what their specification is versus the standard for welding glass filters.
