I've tried it. Thought it was pretty good, but as you might expect it was simply a blending of the properties of both. Not that different from either one alone.
I think cyberblue is the better all around string, and that you can probably get more out of that string by itself at the right tension, than the hybrid.
However, having said that, everyone is different and I could see where some might like the hybrid the best. For me though CB alone is better.
