Yeah, SCS is my base string library for pretty much everything. I don't have CSS, though.
SCS is not at all redundant with any of the strings you mention. Indeed, the library is a most excellent complement. It would be a different question if you already owned Studio Strings, but even there, I think SCS has quite a lot to offer.Ooh, tempting! I have been eyeing these for a while now, but lately I thought I maybe should go the Spitfire Studio route... But these for 350... Only thing withholding me (besides, well, the money) is that I already might have enough strings with LCO, OACE and Spitfire Solo Strings... I always fear redundancy, especially when money is involved.
