A pleasant surprise awaited me when I was handed a set of the Prince Poly EXP 16 to try. I knew little about the Prince Poly EXP 16 string before I tried it. I have enjoyed the Prince strings I had used in the past (I enjoyed playing with the Prince Syn Gut w/ Duraflex as a junior, as well as the Prince Tour in my college career), but I had never heard of the Poly EXP. And after playing with it I had found another Prince string that I really liked playing with.
I strung up the Poly EXP in my Prince TT Warrior MP at my standard 56 lbs for a polyester (I typically do 56 lbs for polys and 58-60 for multifilaments). It was a relatively easy string compared to other polyesters because of its smooth texture and slightly softer feel.
After just the first shot in the warm up I immediately noticed the incredible feedback and “pop” I was getting off the string bed. At contact the ball seemed to explode of the racket, resulting in a lot more power than I was used to out of a full bed of polyester.
Off the ground the Poly EXP felt excellent. I was able to generate large amounts of pace on the groundstrokes and a decent amount of spin to bring the ball back down into the court. Precision and control was slightly less than normal than other polyesters, but since I enjoy a more explosive and responsive string I did not mind.
Volleys and serves were also nice with the Poly EXP. I would have liked to be able to generate a little more bite on the ball, especially for knifing the volleys, but the pace I was able to generate, especially on the serve, was awesome! I was definitely hitting the big flat serve up the tee with a little more juice than normal…
Tension maintenance was good, but not great. It maintained tension for most of the life in the string bed (a little over a week), but started to lose tension towards the end. Durability was about average for a polyester string.
Overall I was extremely pleased with the Prince Poly EXP 16 string! I had played the Prince Tour string for a while during my college career, and definitely felt that the Poly EXP was a significant upgrade from the Tour (even though I did like the Tour a lot). The power and “pop” I was able to generate would be extremely hard to match from any other polyester on the market. If you enjoy a lively polyester with lots of potential for power, like I do, then I definitely would recommend giving the Prince Poly EXP a try!
