As a poly-based monofilament, Big Hitter Silver is a control string designed for experienced players with long, fast strokes. That said, with its flexible construction, it packs more rebound power than the average polyester string, which means Chris had to tinker with the tension to dial in the control. He said, "Big Hitter Silver offered a decently lively response for a co-poly, and I would definitely place this string on the softer and livelier side of the co-poly spectrum. After hitting with a set, I restrung and went up 2 pounds (to 54 pounds in a Head Speed Pro) to add control to the stringbed. With the tension dialed in I found excellent control and just enough power to help me put shots away. I felt confident swinging aggressively and didn't have to worry about overhitting."

For Michelle, this string's impressive control never wavered, and it didn’t come at the expense of power. She explained, "What I love about this string is that I could install it in a stiff power-oriented racquet to get the control I need, but I never felt restricted in the power category. Even after a couple weeks of use, when the string had settled in — possibly even bagged out — it maintained control. For me, it still gets categorized as a control string, but I think you can really juice control and power out of this string depending on the tension and racquet it is installed in."

Although it lacks the ultra-sharp bite of Tourna's Big Hitter Black 7 or Silver 7 Tour (both shaped polys), Big Hitter Silver gave our testers more than enough spin to effectively hit their targets. Needless to say, Michelle was impressed with the spin potential of this round poly. She described, "There's something I love about round polys; there are no frills yet they still have good access to spin for players like me who have a more linear swing, rather than an aggressive topspin motion. With that being said, I never hit a ball with this string and found my shot lacking in spin. This string has great snapback, and I felt the ball load up with spin whenever I asked it to with my mechanics."

For Chris, this co-poly proved quite versatile in the spin department. He said, "I was very happy with the spin I was able to get on my shots with Big Hitter Silver. I liked the way the string pocketed the ball before releasing it with good rotation. I found ample topspin to roll lobs and angles, and to keep my drives dipping inside the baseline. When I knifed a slice backhand, Big Hitter Silver helped me skid the ball low and make it tough for my opponent to dig out."

One of the standout features of Big Hitter Silver was the comfortable feel. In addition to being a great option for those who want a more arm-friendly poly, this string's softer construction allowed Chris to string it tighter for control without losing the sweetspot. He said, "I found a softer feel from Big Hitter Silver than the co-polys I typically play (like Solinco Hyper-G, Tecnifibre Razor Soft, Head Lynx Tour). Even when I bumped the tension to increase control, I still found Big Hitter Silver to feel forgiving for a co-poly."

Although Michelle gravitates toward stiffer strings, she definitely appreciated Big Hitter Silver's softer feel, especially when paired with a stiffer frame. She said, "I was really interested in trying this string because I know a couple of players who use a Pure Drive Tour paired with Tourna string, and I wanted to see why they make it their setup of choice. I understand now, and I loved the feel of this string in stiffer racquets. It did a great job of lowering the shock, and it never felt too soft or mushy. While I tested it mainly in the Pure Drive Tour, I also had it in my Wilson Pro Staff RF97, and enjoyed a comfortable pocketing sensation at contact."

All strings lose tension over time, especially softer polys like Big Hitter Silver. Although this often leads to control problems, Michelle was impressed with how long this co-poly held its optimal playing characteristics. She said, "I found the playability duration to be very similar to other silver strings on the market, and there was not a noticeable moment when it dropped in playability for me. It was one of those strings that I could keep in my racquet longer, and it still maintained control and snapback."

"My only downside hitting with this string was that when the tension dropped out it got a bit launchy," said Chris. "Going up in tension helped keep the string playable longer. Giving this string a slight pre-stretch (before or during stringing, if your machine has that functionality) helps maintain the tension, but at a cost to the ball pocketing capability.
