There are five different sections sizes for strings available from VSL. To my ears, the best "second violins" are the respective next smaller sections, eg. Appassionata / Orchestra Violins, or Orchestra / Chamber.
What I like even better is the same approach as above, with Dimension Violins added as the icing on the cake, e.g. five as First, three as Second Violins. This will allow for unparalleled agility and endless sonic options. Much better than "Second Violins" which wouldn't be much more than an afterthought to the actual First.
Absolutely agree! That's why I combine different libraries! (for Cyril :))
