need different gauges and colors. specifically white. yet this is a great great great string!

Customer very happy with the feel! And let's face they look great in this racket!

ntrp 4.5 male, all court, heavy spin on fh/bh, using on a radicalPro (orange paint job).
definitely feel/see more spin/bite on the ball, especially on serve (slice, kick), compared to my typical strings (lux rough).
had to string ~38lbs.... tried at 48lbs, and it felt too stiff, needed to swing harder.
compared to ultracable, it feels livelier (but still stiffer/not as comfortable than lux rough)... i attribute that to being a 18g (vs. ultracable is 17g).
not very durable... broke in 3-4h of play, which is ok, as i expect that in a spin oriented string (square+thin18g == more grabby == more string movement == more sawing of the mains)

only con is if i'm playing another spin player, and i try to "block" the ball defensively... the ball tends to play the racquet. i need to commit to swinging on my groundstrokes. i find controlling touch volleying against heavy topspin/slice tougher (but that's ok, since touch is not my strength/goto weapon anyway)

The strings were for a customer. He liked the strings alot! Bite and spin!

I was recommended to YTEX by a Germanteaching Pro, who also competes at a very High Level. I already respected his input, but when i got the chance to try YTEX Square Sharp for myself i got to formulate my own objective opinion. Wow, it was apparent from the first couple of minutes hitting that the unique square shape of the string grabbed the ball unlike any other string i'd played with before. The strings also have amazing precision on touch shots with the 18G version, did i mention spin? Love the Lime color, and durability seems to be up to par with some of the higher-priced alternatives. Ivor was kind enough to add some extra goodies with my first shipment like a very cool red shirt and a stencil kit, that goes a long way. Just do yourself a favor and try these string, your game will be rewarded in every aspect!

great string to play with but a pain to string

High quality

Super Spin

It’s giving my opponents trouble returning my shot because of the spin.
String tension is 55lbs. Will try 50 next time.

These are one of those strings that make you want to go for shots! The bite you feel at contact combined with the sound is like the sound and feeling of a basketball going through the hoop swooshing through nothing but net. Love the spin you get from them as well!

Plays real well and has strong durability. Also do a hybrid with Hex X and microfiber x

Best strings ever !!!

I strung my prince ripstick 280g with a set of protour lime @48 lbs. with this setup, i can practice serves for hours, hit with the ball machine until the battery runs out or feed numerous carts worth of balls with 0 discomfort anywhere in my arm or shoulder. this string at this tension is extremely forgiving, so much so that it almost feels like synthetic gut or multi. make no mistake, though, it plays like poly as was evidenced by the ability to hit offensive shots from a defensive court position. i noticed considerably more spin than from my usual syn gut setup and there is no wear or notching after 6-8 hours of use. i would say that protour lime the most comfortable poly i've used up to this point (although much of that could be due to the tension). this may be a good candidate for a player's "first poly".

Love the spin and feel of these strings. I’m Someone with frequent arm injuries and I’m finally able to enjoy the spin of a poly without risking injury.

I ama recreational player in the 55-60 age range. I feel like I've been trying to find the right combination of power and spin while also being 'arm friendly'.

I strung "Darth Vader" (Wilson Pro Staff 98 v12 315g) with Trivoluton Black at 48lbs. It took less than 3 games of play for me to adjust to the incredible feel of the ball on the string bed the Trivolution has. Coincidentally it took about that same amount of play to decide that Trivolution is my new favorite string.
