This is a better alternative to Wilson NXT, and lasts longer too. Great string.

I have been using these strings for a while now. Good amount of spin and very arm friendly!

Soft co-poly strings....nice amount of spin as well! Love the color as well!! Ytex keep bringing us more great products!!

I've been using the Square Black on customer's racquets for a few weeks. Feedback has been excellent.

I was very impressed with the amount of spin I was able to put on my balls with this string. The comfort level was also very pleasant.

What a great string, has it all, good power, great spin, great feel and comfortable. Tension maintenance is also top notch. Can't say enough good things about this string, definitely a keeper!

I am using in the crosses with hexagon x in the mains. Had been using syn gut in crosses but this string seems to be soft enough and produces the firmness I was lacking from the SG. I have suffered tennis elbow in past, i try to keep the string bed soft. So far I have really enjoyed playing with this set up. I can swing with confidence.

I loved the way the Protour Black 17 gauge string really grips the tennis ball and imparts a good amount of tospin and allows the ball to remain on the string bed long enough to allow for maximum control.

I’ve been looking for polys that would not hurt my arm for a long time! Love these strings! Spin, comfort, feel...all perfect! Pretty sure these are mine for life!

This string is great. It works well as a hybrid. This string plays better than a lot of others I have tried that were double the price.. For the price I don't think anyone would not be impressed. I put this in a friends racket to try (his normal- Solinco). He requested this string again for his second racket.

First of all, the package arrived 3 days after i sent in payment so great service!
There is much less coil memory than the Quadro twist so a lot easier to string up.
Play testing by high level juniors claim playability, power, control, feel and durability all seem to be very similar to the Quadro twist.
At the lower price point, it's a tremendous value!
Thanks Ytex!

This is a great feeling string but durability is what really stood out to me! I used this as a main with a poly cross and was surprised at how well it held up. This set up really let me have to free power and really flatten out the ball.

Wow! I haven’t hit with synthetic gut in over 20 years. I new the strings would be comfortable, but to have the same control and spin as I did with polyester, my mind was blown. I’m 100% behind this string and my high school teams will be using it as well. It will be so much better for my old shoulder as well! Thanks YTEX!!!

After much tinkering with my Prince Pro 100P I have settled on Quadro Twist as my mains and the Protour white as the crosses. I feel like the white version of the Protour has a great feeling pop to the string. The black in the 16g has a little more power which in my setup that wasn't what I was looking for in a cross string. Overall the Protour is a great line of your basic round poly. It can be played as a full bed or complement a textured string as a cross!

This is a great string. i used to use RPM Blast and tried this as a comparison. This string to me out performs blast especially at the net. I just ordered a reel so I don't run out. I string for a lot of others, so they will be getting some also.

I've been using Y-Tex strings for over two years now, and I would put them against any other string on the market. I've used countless different brands during my playing and coaching career, and I can say with absolute certainty, Y-Tex strings are the best in the business.
Square-X and Hexagon-X are my two favorite in the Y-Tex line due to their longevity, feel and holding tension compared to any other poly I've used prior.

I love playing with this string in my pure aero. Plays exactly the same as rpm blast but is much cheaper. Great spin. Enough power and control. Love it.

One of the best strings I’ve played! I’ve tried Weiss canon black 5, genesis black magic, solinco, technifibre black code, pro hurricane tr, rpm blast etc and so far square has been the best for me! I love that it’s square shaped profile allows for more string movement for snap! This also allows for better grip but longer lifer due to less friction! Great people and product! I personally know the owner Ivor and he’s a very down to earth, great guy who loves the sport and helps others to love it more by supporting coaches, stringers and players alike! I consider my self to hang around 5.0 range give or take and I hit massive spin aswell and this string just plays amazing thru it’s whole life and very comfy!

I have a client that changed from wilson NTX to this string due to the wilson string didn't last as long as the Microfiber-X. He loves the spin he gets and the longevity of the string. I just strung two racquets using Microfiber-X.

I got a chance to hit with it this weekend and loved the top spin it created on my forehand and serve. I will be purchasing more of this and recommending it to all friends and clients who's racquets i string

I recently received these strings and I have to say they are very comfortable, spam friendly and nice power. 10/10

I've tried the black and now the white. While I like the white for serves, the white is outstanding on ground strokes. I'm hitting the ball 2-3 feet deeper in the court making returned shots shorter. This gives me time to move in and hit the winner. Great new string.

Good string at a great value . Plays a lot like RPM blast or black code but way better value

I loved every aspect of the experience. The strings are awesome! Very simple, easy shopping experience.
