Comments: Worst string I've ever put in a tennis racket. Put this in my Head IG Prestige Pro at 54 lbs. I had Solinco Tour Bite 17 in it before this, and it was like playing with two different rackets. Got no spin and absolutely no control whatsoever. I'm a 4.0, borderline 4.5 player whose main strength is consistency, and I was spraying routine forehands and backhands 5,6,7 feet long. Completely lost my serve due to the of the lack of spin. Not only do they not play well, they don't even feel good. I saw the reviews that this string would break in and play and feel better, but I've played 5 competitive matches with these strings and I haven't enjoyed one point with them, and the feel hasn't gotten any better. There is a weird vibration, which I think led to shoulder pain. I'm 20 years old and I've been playing for 8 years, and I've never once had shoulder pain before.

Comments: A step back. Not as good as previous releases. This edition does not hold characteristics as older versions used to.

Comments: String is very, very nice but maybe a month of play and they already broke I'm happy I got the triple pack version. Well beside from that I believe this is a good string and people reading my feedback should test this string out.

Comments: In response to Michael, after about a month of play these strings are too lively when fresh. After they really settle in (5 or so hours) you have more of the pocketing and control. I find this to be the same case with Pro Line 2. This coincides with Michael's test report. They are really very similar only this string will retain more performance because its lighter and is the latest Pro Line co-poly tech from Kirschbaum. Really impressed. It is like a cool blue color. It rocks.

Comments: I put these bad boys in my Volkl Power Bridge 10 Mid at 45 lbs and all I can say is wow. There is nice power, nice spin, and nice control.

Comments: I have been playing with Pro Line 17 (red) and liked it. Began to demo racquets so at the same time tried new strings as was suggested by Tennis Warehouse. As usual they knew best. The Evolution 17(blue) was just as advertised. It added power and additional spin without losing control. It added a little MPH and action on the serve and still gave me the feel for lobs and touch volleys. From the first hit it was great! I will now use the Evolution 17 and not buy a new racquet until spring. I don't break strings so the 17 should perform just fine. I am looking forward to see how it performs in the heat of the Texas summer! I will admit the blue strings do help to focus between points!

Comments: This string is just great. Great spin without the hard and harsh feeling of most textured polys. Holds up and performs just like Pro Line 2 only a little more explosive in the power department. It is pre-stretched for better tension holding (like all Kirschbaum strings) and it is a co-poly which makes it more comfortable. It represents the latest technology. For a players racquet (I use a Tecnifibre TFight 325), the tension is best around 50 to 53 lbs. Also I think the blue color is rad.

Comments: I've been playing with Proline II 1.25 strings for roughly 8 months. I love the control you get off of the bed and that I can swing out fully and keep the ball in. So I tried the Evolution version of the string and they are similar in some ways. They are a little more lively with a touch more spin. The extra power was welcome on my forehand and serve, but I felt that I had to hold back on my forehand to keep the ball in. I might be able to adjust to the string, I'll give it a few more tries. But side by side against the Proline II (black 1.25), I was striking the ball much better. I should also point out that while both racquets were strung the same, the Evolution racquet was fresh, while the Pro Line II black was going on 12 hours of play (still had more control and I could swing out more). Proline II black is still my favorite!
