I have been using 18g Hyper G in a hybrid in the same racquet I have been using 17g Cyclone (both orange and yellow) hybrid and have found myself preferring the Hyper G. I would agree that the spin level is similar, but Hyper G is more comfortable, a bit more powerful, and tension maintenance is definitely better. Using an ERT 300, my dynamic tension in a racquet played approximately 14 hours is showing the same dynamic tension as a racquet played 1.5 hours. Additionally, I have found Hyper G to provide a more consistent response from right off the stringer into 14 hours of play (most time I have on one of my three racquets strung up with Hyper G, testing cross strings so the racquets are in a rotation). Control is there with both strings, but I have found Hyper G to open up the sweet spot a bit more and have found better control on off center hits vs Cyclone. In the end, I have found that I definitely prefer Hyper G over Cyclone and will most likely be purchasing a reel once my packs disappear.
