I have this Tecnifibre Triax 16 gauge strung on a new Head Graphene XT Radical 102 square inch at 57 lbs. I'm a solid 4.5 player who's been playing since 1991 and string my own racquets. I have to say I really like this string. I went with 16 gauge for durability and control. It's similar to polyester and behaves like it without the harshness. Feels more like a multifilament. In 2 sets I had one cross string in the sweet spot move a little that I moved back in place. I just took out my racquet to look at it and all the strings are in place. This will definitely be my new string and even though it's a bit pricey for me it's worth it. I'm done buying so called soft poly's experimenting with different types and kinds of strings. Now I can buy one and be done with it. I was surprised from other popular online tennis shop's player reviews when they commented on how the string didn't or hardly moved so I had to try it out. I'm really glad I did.
