First of all, have a quick and effective recover!
Then about strings, if you want to try the new synchron set-up I would recommend you buy "Synchron-ized Appassionata Strings" instead of Synchron Strings I. The reason is they are based on the same (dry) sampling technology you were used with VI products, and they can match sound and ambience of both the old and the new world.
User's opinions about Synchron Strings are different, some people really criticize and blame Synchron, some other are happy... generally speaking they have very good recording, amazing shorts, nice ambience, but they have some pretty fake sounding articulations (e.g. sfz, fp etc.) and some synthy legatos and cross fades.
Opnions about Synchronized Appassionata strings were almost universally positive instead.
(My personal favorite anyway still are the Dimension Strings: in combination with VI Pro and MIR 24 they are the more flexible and more realistic Library ever created).
In case you own Vienna Ensamble Pro, I would recommend you buy the upgrade to VEP 7: it includes "Epic Orchestra 2" and it's a perfect way to get a selection of samples from Synchron, Chamber and Appassionata strings in the new Synchron Player, so you may test the way it works and how they sound, and take your favorite choice.
