First up is Wilson’s new Hollow Core string. Wilson has brought some new technology to the game with this one, as it is the first string to offer an air filled core.
Priced at $13, I expected this one to offer performance compared to a good multifilament. I have to admit, I was sorely disappointed. For me the string lacked feel in a big way. I felt very separated from my shots with none of the control or touch I’d expect from a synthetic gut in this price bracket.
Durability was about average for a synthetic gut string and it seemed to hold its tension ok. I wasn’t getting the spin I usually get as I had to temper my swing due to the power I was finding with Hollow Core.
All in all I was not a fan but did pull two pluses from testing this string: there’s an impressive amount of power from Hollow Core and secondly it offered a comfortable hit without feeling overly mushy. However, if I were looking for a performance synthetic gut I would go with Wilson Sensation. It’s almost half the price and just blows the doors off Hollow Core as far as I’m concerned.
Next up is the new Luxilon M2 Plus tennis string. At $19.50 a set, this is an expensive co-polyester string. While almost all co-poly strings are monofilaments, this one breaks the mold with its multifilament construction (Gosen Polylon Polybreak and Gamma Zo Tour share similar construction). With that multifilament construction comes a softer response.
On shots hit outside the sweetspot M2 Plus felt more forgiving compared to many co-poly strings — although still far from the comfort of most nylon multifilaments and obviously natural gut.
I liked the amount of spin I could generate with this string. I was able to take a really good cut at the ball without sacrificing control and could turn a lot of that racquet head speed into spin. It also felt like I was getting some good ball pocketing from M2 Plus. I was digging the amount of bite I was getting on the ball, especially on serves and approach shots.
As with most co-poly type strings, durability was very impressive. With better than average tension maintenance, I found I could keep M2 Plus in my racquet longer than most poly strings without fear of breakage or a massive loss in performance. With a string like this, though, I’m going to be cutting strings out before I break them unless I’m testing a really open patterned racquet.
All in all I was very impressed by this string. It’s expensive, but along with M2 Pro, it is the softest I’ve found in the Luxilon line. M2 Plus is well worth a hit if you like your co-polys soft and spin-friendly.
I hit both strings in a variety of racquets we have been testing here at TW — at least 9 different racquet models for Hollow Core and closer to 20 different racquets for M2 Plus.
