Hi Danleigh,
I’m going to suggest 8Dio Adagietto (their new ensemble arrangement of Adagio) over Cinematic Strings 2.
It’s cheaper at the moment for the intro price, it sounds just as good, and the spiccatos in it are just gorgeous whereas with CS2 I have to work a bit to mold their staccatissimo articulation to get a sound I really like.
You wouldn’t regret CS2 at all, it’s very user friendly and sounds wonderful overall. But for trailer writing I suspect you’d find the Adagietto spiccs to be more suited.
