"Wow! A responsive polyester with pop! The increased power is very easy to control. It is not nearly as harsh as most polyesters on the market. Even with heavy topspin, the strings don't move. Generally, I'm not a fan of polyester. This string is the exception." 4.0 male serve-and-volley player using Prince O3 Speedport Pro White MP strung at 66 pounds CP (Wilson Sensation/Prince Synthetic Gut w/Duraflex 17/18)
"Very arm friendly. Great spin. Impressive power on serves." 4.5 male baseliner with moderate spin using Head Metallix 6 strung at 53 pounds CP (Wilson Sensation 17)
"This string is a great compliment to the heavy topspin game. Control is simply outstanding. Touch and feel are slightly lacking, which is typical of the breed." 3.5 male baseliner with heavy spin using Prince Tour Diablo MP strung at 58 pounds CP (Luxilon Alu Power/Gamma Synthetic Gut 16/16)
"This string plays well from the first hit. It has decent power and control on serves. Comfort is on the low end." 4.0 male all-court player using Head Youtek Raptor OS strung at 50 pounds LO (Luxilon M2 Plus 16)
"The feel and power are exceptional. This is a comfortable string with above average power. Spin is less noteworthy, but the control is impressive. I would not hesitate to try this string in a different frame." 4.5 male all-court player using Head Metallix 4 strung at 57 pounds CP (Gamma Zo Tour Rough 16)
"Marvelous control and spin. Comfort is surprisingly high. The absence of a "trampoline effect" makes the power very controllable. Tension maintenance is the only negative." 5.0 male all-court player using Wilson K Six One (76 holes) strung at 60 pounds LO (Wilson Hollow Core 16)
"You can feel the strings biting into the ball. Notching starts fairly early. Overall, this is a good string, but durability is an issue, which is not out of the ordinary considering my stroke style and open pattern." 5.0 male all-court player using Head MicroGEL Extreme Pro strung at 49 pounds LO (Signum Pro Poly Plasma 16)
"Spin potential is excellent, but the ball tends to sail. Seasoned poly veterans should string tighter for control. I also think this string would perform better in a hybrid. Poly in both directions is only good for players like Rafa." 4.0 male all-court player using Prince O3 Speedport Tour (hole inserts) strung at 51 pounds CP (Tecnifibre Pro Red Code/Gamma Synthetic Gut 18/16)
"This string feels great right out of the box. Impressive power and spin. After five hours, control suffers." 5.0 male all-court player using Wilson K Tour strung at 66 pounds CP (Luxilon Timo/Head Synthetic Gut PPS 18/17)
"Big power and spin. Great for hitting against medium pace. Playing against heavier balls creates a much stiffer feel." 4.0 male all-court player using Volkl V1 Classic strung at 52 pounds CP (Unique Tourna Quasi Gut 16)
"Crisp and clean. Players with high head speed will appreciate the added sense of control. Some difficulty on touch shots, but the overall playability is above average. The sweet spot is not very big, but it is very sweet." 5.0 male all-court player using Wilson K Blade strung at 50 pounds LO (Babolat Hurricane/Wilson Sensation 17/16)
"This is a crisp string with excellent power and spin. The tension maintenance is above average for polyester. Even with a 10% tension reduction the string bed is on the stiff side. The strings do not move." 4.0 male all-court player using Babolat Pure Drive + GT strung at 56 pounds LO (WeissCANNON Scorpion 17)
"Remarkable combination of spin, control, and power. Comfort is on the low side." 3.5 male baseliner with heavy spin using Babolat Pure Drive Cortex strung at 55 pounds CP (Polyester/Natural Gut 16)
"This is a playable poly with some serious spin potential. It does fairly well in some areas, if not great in all." 6.0 male all-court player using Wilson K Tour strung at 52 pounds CP (Wilson NXT 17)
"The lack of feel and playability hinders control. The spin and tension maintenance are good, but comfort and touch are on the low end." 5.0 female all-court player using Head MicroGEL Extreme Pro strung at 45 pounds CP (Natural Gut 16)
"High coil memory slows down installation. During the first two hours of play the string feels crisp but not stiff. Like most polys, this string excels at control and spin. Power is also good. Feel is a tad low, but not completely dormant as with some polys. Over time the feel improves, while spin and control remain consistent. After 6 hours, however, the string begins to lose power and feel. By the eight hour, harsh vibrations emerge until, finally, the string goes dead." 5.0 male all-court player using Yonex RDS 002 Tour strung at 50 pounds CP (Tecnifibre X-One Biphase 17)
