I run SD 2.0 with one of the NY Studio expansion pack, as well as the older DFHS library, all triggered by a trapkat setup. No complaints really, though if I had a good room to mic my acoustic kit in (or good mics to begin with, lol), I'd never touch it again.
The ability to mix / match in 2.0 is a bit limited compared to the older version, but still it works very well, and has better tools in place for folks who are just doing programming.
