Had the opportunity to try the nano-classic (the original nanofill composite invented back in 2003 by Voco), Grandio. This exceptionally-easy-to-handle material has a low resin content, yet is much more readily polishable compared to Grandio SO. It has a filler content of 87% (Grandio SO is 89%) but features better Vickers microhardness compared to Grandio SO (285MHV vs. 211MHV). It also has an ultra-low abrasive rating. It’s great for situations like this Class V, however, its slight increased translucency relative to its newer brother makes it less of a chameleon optically.
