I've just laid out a Blur Hybrid(specs in profile), and I'm liking the backend; a fairly controlled motion, not exactly weak, but if I miss the release a bit, it kind of fades on the backend. Conversely, if I overhit it, it doesn't go left like it had been kicked. This is pretty much the same motion that BTM described.
As I've been struggling with overreaction on the backend lately, this one has been great, so far(my first c300 since the merger, BTW).
