Sorry, never tried Cyber Blue. I've heard the same things.
Mostly, I'm afraid of what people consider soft". From what I've experienced, most of the "soft" strings are dead, lifeless, and spongy. There are very few "soft" strings that are lively and have good response with feel. PS Energy is one of them. Tour Bite isn't soft, but I would refer to it as "crisp" with feel.
There are way too many polys to try all of them. I find what I like and stick with it.
