Lime string that pops well and full of spin. Adds alot to a fast heavy spin serve and even a flat serve.
Another of my favorite strings from YTEX. Just has so much bite that it gives my one handed back hand Stan The Man vibes that I opponent’s stop targeting my backhand side during match play. Also great to use in a blend with HexagonX red at the crosses and this in the mains.
I did love them so much that after the first set a did buy a full reel!
Square-X Sharp has to be the most spinniest control string I've ever used amazing! If you looking for control and spin this is the string with power you can't go wrong especially if you mix with hybrid with another poly!! Just try one set and you will find yourself buying a reel!!
The lines on the tennis balls in the picture are from the extreme bite from Square X Sharp in the mains of my RF97. I'm a hard hitting 4.5 and use Ytex Square X Sharp in the mains and either MSV Swift or Isospeed Cream in the crosses. It's a great combo. The Square X Sharp gives great spin, feel, power, and control. The round slick coated cross strings add durability and help with tension maintenance, while providing great snapback to help with the spin. Love Ytex and am glad to have found Square X Sharp!
My 1st time using 18g and will not use anything else. I feel that I definitely have more "pop" without any control loss.
I ordered more strings after my 1st time using them.
I use them in a hybrid setup wit natural gut and love the spin and feel.
Tried the 18G, thought they would have a little more pop for for 18G but thye played well. As expected for an 18G, lasted about 5 hours of play time.

Tried ytex on a whim when I heard about square x sharp. Thought it would be a novelty and I'd be back to searching around to find something that would fit my needs and protect my elbow. Immediately noticed a difference. Play tested several others but their flagship ended up checking all the boxes for me. I string an ezone 100 with a full bed of quadro twist black at 48lbs. Spin generation and power with full cuts from the baseline have helped my rally depth tremendously. First serves still pop, but my confidence with kick and slider has gone through the roof. Anyone looking to get into the brand should start here and see what it does for them!
With Twist Purple in my other racquet, Head Exteme MP, I strung Hexagon Red as a cross (40 lbs) to Square X Sharp (42), and along with Purple, found it superior to the smooth poly Protour as a hybrid cross. Whereas Purple seemed to exceed Red in power, durability and control, Red did enhance the spin. The full bed is good, but try it in a hybrid, even as a cross!
On a dare from a YTex FB colleague, I tried Hexagon Red, and while I was at it, strung Twisted Purple in my other racquet, Head Extreme MP, as the cross to the mains of Square X Sharp, 42 in mains, 40 in crosses. It beat Hexagon in durability, power, and control. And yes, beat the smooth polys, Protour, in performance. No doubt it has its market as a full bed, or even main, but consider it as a hybrid cross!
My favorite feature of Protour Blue is the softness. There are very few copolys that I can use without hurting my arm. At the same time Protour Blue provides some additional spin in my hybrid with gut.
I was looking to soften my string bed a bit more as well as trying to increase the snapback of my strings. By adding Pro Tour to the crosses with Quadro Twist in the mains, I feel like the strings still grab the ball since QT is in the mains, but I believe I increased my spin due to the better snapback of the strings now that a smooth poly is in the mains. It also made the overall feel more plush, which is what I was after. I'm very happy with this hybrid and will be using it going forward. I string the mains at 48 and crosses at 46.
I have a small and it just barely adjusts small enough but it is very lightweight and comfortable.
I use Protour as a cross with Square X as the main. Gives me plenty of spin and pop on the ball
