Tennis Express is happy to announce we'll be carrying the full lineup of Poly Star tennis strings! The first and foremost string we're excited to test (as soon as this bad weather in Texas allows!) is of course ATP star Nikolay Davydenko's string of choice: Poly Star Energy. We're particularly excited to test this string due to the fact we've heard from various sources and customers that this string is in fact more powerful than the popular Luxilon Big Banger ALU Power, and softer at the same time. With the popularity of the Big Banger, many people see the downside of it because it is a very stiff string, and hardly arm friendly. From Poly Star PR: Players will find great ball acceleration and pocketing combined with unmatched elasticity and durability in the Poly Star energy. Once you play with it, you'll never ask for more power again, just ask ATP star Nikolay Davydenko, who makes the Energy his string of choice.
