Comments: It is softer than Lux. ALU Power but does not have the same pop or power (but sufficient power). It is similar to ALU Fluoro in softness but not as lively and doesn't feel as nice. Not bad for the money though. Feels better after a few sets. It has a kinda plastic-y feel to it. I strung very low - 48 lbs on a Babolat Pure Storm Tour.

Comments: Good strings with lots of pop and control. Comfort quite good too. I've always used syn guts/multis and my first experience with poly (Lux BB Alu Power) was not pleasant with stiff being the overwhelming impression. However, I liked the control it gave and thought of hybriding a soft poly with a syn gut. Was recommended the Cyberblue by some as being one of the softer polys around, and hybrid that with Gamma TNT2 16 at 52/55lbs. Amazing... lots of pop, great control, and with decent comfort to boot. Can't comment on durability as I sold that racket after a month or 15hrs of play.

Comments: These strings are very durable with great power, but lose too much tension after few sets of play. I have to change strings every 2 weeks.

Comments: Nice string with good power and better control than others I've tried. Watch your tension with this string as the ball really flies at lower tensions. I wish they made this in another color.

Comments: These strings are great. They give such a good feel and hold tension pretty nicely. I crossed them with Cyberflash. They use to be called Cyberpower but they changed it Cyber Blue. Don't know why. They are extremely durable. They are actually polyester, but they feel like synthetic gut.

Comments: This string is definitely one of the best strings I’ve ever used. The only thing that can even come close to this is big banger fluoro. Cyber blue is great in playability and durability. I’m not a string breaker so these strings actually last me 4-5months of playability and they were still on but I eventually cut them to get a fresh batch of this. This is definitely the best bang for the buck.

Comments: It's a great string especially when crossed with Cyber Flash, I highly reccomend it.
