I'm obliged to offer some quick comments, as I have tried each of these strings at least once.
Ytex Square-X 16L - Black is similar to Monogut ZX Black, except the ZX is smooth. The Square-X is a bit less elastic.
Yonex Poly Tour Pro - I only strung up the 1.20 once. I checked the bed with ball bouncing a couple times in a few days. It deflected a lot more than it pocketed and felt very synthetic. I knew I wouldn't like it so I cut it out. Uniquely soft, muted string.
Topspin Cyber Flash - My favorite poly of all time when price is considered. The upgrade is Tour Bite Soft, a little deader and a little softer feeling.
Weiss Cannon Silverstring - Mid-range in price between Cyber Flash and TBS. Not as good spin or feel as the other two.
MSV Focus-Hex - 1.23mm and thicker are very stiff strings. I like the 1.18 black a lot. Basic shaped poly with good spin if you have good technique. It's similar to Pro's Pro Black Force 1.14, except BF is smooth and round, and a great value when you get the reel.
My favorite hybrid for clobbering the ball on ground strokes is Cyber Flash 1.25/Gutex Ultra 1.30 @48/53 in my MW racquet in my signature. I have trouble with accuracy for serves with this setup. It's very plush. I've been trying some other hybrids and CF/Kirsch SG gives me more control on serves and is still nice for strokes. The BF/GU setup in my Biomimetic racquet in my signature is very nice too, but it has a more connected feel than CF/GU and a little more connected than CF/Kirsch SG.
I strung a Klip Legend 17/Black Mamba 1.23 bed @57/52 in my Biomimetic 200 a couple of days ago. I won't get to hit with it for at least another 2 months, but it feels comfortable and crisp with great control and consistency. Damn you Winter!
I also like Head Lynx 17 full bed in my Biomimetic 200 @50. Not so much on the MW racquet. And I'll be trying Kirsch SG 1.25/Red Devil 1.19 @54/50 in the Biomimetic as well. It would help me if the inexpensive strings played as well as the others do. I'm not as concerned about longevity for cheap strings.
Hi Mareqnyc, I would like to ask for your recommendation please. I'm looking for a string that has great spin potential and very crisp feel to "de-mute" my Wilson Clash. The 2nd priority is playability duration. Comfort and power is not really a concern. What would you think is/are a good fit? Thanks!
edit: I'm looking at Ytex Square and Solinco Revolution now but more options are always welcomed.
