NXT control is a great string that is very unique. I think it's more multi than poly but it plays soft like a multi but with low-power. If you need a low powered string thats soft then this one should be given some consideration. I only used it in a full job for some higher powered rackets, but I would imagine it would make a nice durable and soft cross with poly mains. It's only drawback is that it's quite expensive. I remember it being near $20 a pack. It's quite different from all the other NXT strings. NXf tour is a premium multi. And NXT is a multi but Nothing like the tour version. Very crisp feeling but not much power or feel to it.
