Hello All:
Have about 7 hours on the setup and feel I can give a decent review at this time:
Sorry to say I have read most of what has been posted on this string and was impressed with the reviews. Folks on Talk Tennis are very good and reviewing products and honest about what they experienced.
I am not going to produce a full review but give my impressions. I found the string to be very firm and precise. I strung my frame 48 / 44 and should have gone down a few pounds. This is a "TOUR" offering for sure in my book. Not a string for a 3.5 just moving into a poly.. Inside the sweet-spot... magic and spin off the charts...miss the sweet-spot and the power and spin is reduced. Since I was coming off a long lay off like many of us, I was not at my best in finding the sweet-spot and my footwork was sloppy. I was much better on Sunday and maybe the string-bed also was a bit more forgiving due to tension loss and the 90 degree heat.
I found the power to be right in the middle of the scale at the tension I picked. Spin was of course in the upper end of the scale. Backhand slices are wonderful as are slice and kick serves. The launch angle for topspin off of both sides is higher than a standard round poly but right in there with Tourna BHB7 17G and my go to string Volkl Cyclone 19G. The control was outstanding and offered a very linear power / control balance at least for me. Very honest output.. put a good stroke on the ball and make solid contact... string-bed is giving you a true output. Very connected to the string-bed after the 1st 2 hours it was very better.
The response from the string-bed was very predictable and the tension holding is really a strong feature of this offering from Tourna. I am a fan of most of their strings... hate the over-grip..

... the blue crap..
Using this string in a firm or stiff frame might offer some arm concerns. My frame is about 60 RA and might be lower due to age.
Stringing this up was not problem but I had the benefit of advice of others. I can see how a big hitter might break this as it appears to be on the brittle side. Will not be an issue for a player with medium swing speed and length. Hitting the sweet-spot is not a issue for higher level players so the power drop outside the sweet-spot and firmness of the string would be moot.
Again.. I found this string to be a TOUR offering and in my case.. I would love to hybrid my next try with Tourna BlackZone as a cross or Head Sonic Pro (IsoSpeed BaseLine) to add a bit of softness and give to the hitting zone and keep most of the attributes of the string.
Given the Tourna Price Points when buying in reels... hard to go wrong with this in reels. I felt the stiffness of the string was 200 to 210. TW has a value posted for 16G and RSI Mag says 198 for the 17G. I was testing the 17G in a 102 Head Size with 16 x 19 pattern.
Thanks to
@Injured Again for the play test sets... And to all the great info in this thread. I missed the Talk Tennis play test on this one and really enjoying doing this short review.
Happy Hitting All.. Be safe out there!
