Comments: I ordered my '13 Aeropro drive GT+ with poly strings. The combination was way too stiff resulting in immediate elbow pain never felt before. Replaced it with a multifilament strung at a lower tension 50lb. Initial first hour play test felt very crisp, smooth power delivery, and had a satisfying pop feel. I'm a flat ball hitter so string movement wasn't an issue. Very comfortable on the arm, wrist, and elbow. Having the right string is like driving with the right performance tires.

Comments: It felt stiff for a multi but not uncomfortable. It maintained tension for about 5-6 hours, then felt flat. It provided minimal spin, though curiously, I served very well with it. I'm a 4.5 player who plays with moderate spin and power.

Comments: I felt I didn't get the topsin and the durability. After reading these reviews, I felt the opposite. It does get mushy and lacks control. I used a Head YOUTEK and am a 5.0 player. I broke these strings in about 4 hours of play. I prefer the Volkl V-Pro strings.

Comments: I have been playing this string for about 2 months now. It is a very good multi. I get good durability, spin, comfort and control compared to other "premium" multi's like SP Micronite, NRG2, BP X1, NXT, and LaserFibre Super Natural Gut Phenom. I think it is priced very reasonably too,I have a reel and my buy another.

Comments: Great durability, soft on the arm, tons of power...Power Fiber is a great string on the crosses with a co-poly on the mains.

Comments: Love this string and there's nothing else I could say. It's really better when compared to other multifilaments. Everybody should try this.

Comments: Being a frequent string breaker with arm issues I am always looking for the perfect combo. The problems with most multis is they break too fast and have a tendency to move around; the plus is lots of pop and touch with less impact on the arm. Using the Power Fiber 16 as a main and a nice soft multi NRG2 or Maximum Touch (even better) as a cross is a great hybrid. An arm friendly combo that has some durability along with playability. The Volkl string is a bit thicker 1.32 and stiffer than other multi's and adds some durability to the combo along with less string movement. The softer cross adds the pop. Play with the tension, I string the Volkl down a lb and up the cross.

Comments: This is my second set, and it is a great string for the first 20 hours of play - crisp. After that the tension drops about 20% and becomes mushy and becoming more difficult to control the ball.

Comments: When I first got my new racket, I actually asked for this string, but the stringer didn't have it in stock, so I had to choose Babolat XCel Power. I was fairly satisfied with the racquet after that, but when I had it restrung I chose this. Right away, I noticed a definite power and spin improvement, particularly on the serve. It also had better feel, but I had to take out the vibration dampener. My groundstrokes were deeper and had more spin. I've used this string many times and have never had any durability problems. I was surprised that even with the same tension I had such a power improvement. As far as I'm concerned, you won't find a better multifilament for spin and power, and it's also easy on the arm too.

Comments: Nice multi for durability. I've been looking for a multi that plays and lasts = and this one is as close as I have come. The 16 gauge is 1.32 mm which is a bit thicker than most 16g strings. They play stiffer than some of the others Wilson nxt and Tecnifibre nrg2 so I have been stinging them down 2lbs which adds a bit to the feel. I have also tried them as a main with NRG2 as a cross which added some pop and feel. Will also try the new Hollow core Pro as a cross and Weiss cannon Explosive as a cross to see if I can get a softer hybrid feel going. If polys are a bit hard on the arm this Volkl could be a nice alternative as a main.

Comments: This string is good because it has power and spin. It has decent durability. It breaks in about 10 hours. I am 10 and use a Volkl tour 6. The tension I use is 56lbs. I use this string on the mains and Toa gold on the crosses.
