Hi guys, I had been looking for reviews of Polystar Strike and I only found 1 review. So I went ahead and bought every Polystar string to give them a try. The first string I tried was the Energy. I heard some good things about it and also read that some pros are playing with it. To tell you all the truth, I was disappointed with Energy. The first time I played with it, I played for only 1 hour, it felt ok, crisp, quite powerfull, decent feel, easy on the arm. The 2nd time I played with it on the next day, it had lost quite a lot of tension, a bit more then what I am used to in a poly. But I stuck with it and played with it for another whole hour; so as you can probably imagine, it had quite a lot of power, not much feel, I didn't really enjoy it. So I then decided to try Strike. It wasn't the best string to string with. It is not a smooth string, it is textured, so I had to be more carefull while pulling the crosses. After being a bit disapointed with Energy, I did not expect much from Strike. I went for a long hit yesterday, and BOY what a good surprise I had! It is not as powerfull or soft as Energy, but it felt crisp, great control, good amount of power and great spin as well. It was just such a good combination of everything. I recently tried Pacific Polyforce, and they seem quite similar, but the Polystar would be a much beter version of it, better in spin, feel and control. So, for €59 for 200m, it is also a great value, there are lots of strings out there costing at least twice as much that aren't near as good. As for holding the tension, I played for almost 2 hours and the strings hadn't lost much tension. I am playing again today and I will update on how it felt again today.
