If you want a string that hits like a stiff string but with comfort/power/control/feel, this is the string.I string my Wilson Pro Staff 97 at 58/54lbs. I do a lot of weight lifting along with playing tennis so I'm a big hitter. This string puts a noticeable amount of spin on the ball with a lot of control and added comfort. On top of that, this string holds tension and durability exceptionally well. I'm on my 3rd week of having this string in my racquet and I have not noticed, if at all, any tension drop. I still get the control I like at 58 lbs in the mains. I may even go a little higher and string it at 60/56lbs to see if I can swing even harder while maintaining the comfort and feel. Because I have my crosses strung 4lbs less in the crosses, it adds more feel/comfort and helps tremendously at the net for serve and volley. This is all granted I don't mishit and have correct form with every shot.Definitely worth the money and price. I came from a hybrid of multi in mains (NRG2) and poly in the crosses (Razor Code) and this string does it for me primarily because I don't have to restring due to a broken string.
