Dropped the 17g down to 40lbs and love it in my Yonex Ezone DR 98. I have been stringing a few friends racquets with this stuff and everyone has loved it. Give it a try, you won't be disappointed.
@USPTARF97
Do you find BHS7T harsh on off center hits at times? Been having some shoulder issues (unrelated to string) so thinking to go gut/poly for a while...
Are you still using gut/poly sometimes?
I don’t alway break strings, but when I do -

Note the break is virtually identical to post #383. While I didn’t string this particular racquet, it was done by a known source that I’ve had no issues with previously.
IMO - note the twists in the strings adjacent to the break. My belief is that the thermal treatment that gives the string it’s extended play duration also makes the surface unusually brittle, and is then unusually susceptible to failure from twisting, sharp angles, and aggressive clamping.

@USPTARF97 I agree completely. This wasn’t an extreme play impact/shear situation.
My impression though is that the stringer has strung literally thousands of racquets, with essentially the same level of string handling care without significant issue. The appearance is that there appears to be a trade off for the enhanced play duration (and overall feel and play characteristics) of this string, which is the need for unusually careful handling during stringing.
Even with this potential limitation, this is my current string of choice. My hope is that fewer people will have unnecessary string breakage if they’re aware of the likely cause.
There is definitely an issue with the string.
It's not random that multiple players on this forum have had the exact same issue with the string breaking around the grommets.
For me, after 6 months of use, I've had about 1/4th out of 20+ string jobs break like this.
It's an amazing string, that's why I keep using it despite this annoyance.
I hope Tourna would look into it seriously.
I also wish they'd come out with a round slick version of this string.
Don't really understand the praise, BHB7 is superior in every aspect.
Nope, I think it's less powerful, gives more control and the spin is better. Tension maintenance is worse, true. But as it said above, it's probably my personal impression.Isn't BHB7 more powerful than S7T but with worse tension maintenance?
Wilson 6.1 95 18x20 BHS7T @ 46. Been getting 8-10hrs and then cutting it out. Great playability the life of the string bed. At $6.00 a frame I can’t find a reason to use anything else.
Why only 10hrs? Just tension loss or something else?
Strings start to notch a bit, loss of tension but not unplayable. Avoiding waiting for it to get stiff before changing the strings.
Hello All:
Years ago... when Big Hitter Black 7 17G was released.. I picked up a reel and set out sets. This is the play testing data that was produced.
Hope this is of some help. BTW.. it was released in 2011.
Below is the TW review..
Does it stiffen up noticeably later in it's life? I have noticed that a few times with various polys. If it does, I might have to drop this one from my short list of strings to try after my current reel of WCUC is done. I don't like that characteristic in a poly at all.
Weiss Cannon are good strings no doubt. WCSS I played for awhile. Easy on the arm but the 50% loss of tension was too much. By the end of the first set would be playing with a completely different set up.
Poly strings stiffen up mainly from becoming notched and sliding less later in their life. The loss of tension and notching of the string provide a stringbed that is stiffer, provides less spin, and loss of control.
BHS7T is more durable in this sense than most polys I have used. Only has a tension loss of about 20% where strings like Alu Power lose 45-50% and the notching is minimal with BHS7T. That being said it isn’t indestructible but it maintains everything that I want out of a poly string for 8-10hrs. Can’t ask for much more.
So would you say that BHS7T starts locking after 10 hours or so for you and that's the difference?
I'm not necessarily afraid of trying a poly string with big tension loss, but I don't like it when the feel changes noticeably.
I think WCUC is close to 50% tension loss according to TWU, but I find that it seems to level off after the initial drop. I've had that experience with quite a few polys. I just let my freshly strung frames sit in my bag for a week or two and I never experience that drop. I can play WCUC happily until it breaks which can be up to 30 hrs. depending on how much time I get in singles vs doubles. It doesn't lock up at all in my experience. The only thing that happens besides notching is the crosses tend to flatten a bit, but it's not such a big effect on the way that the strings grab the ball that I feel it would make me want to go to fresh strings.
I like these types of anecdotal reports from people on strings. It really helps narrow things down if you get a few similar reports from people on things that might be a deal breaker, and string life with polys is a mixed bag. Having been able to find several polys over the years I can happily play until breakage I don't want to waste any time or energy on strings that I likely won't want to play until they break. I know a lot of people are ok with cutting out strings, but I haven't had to do that in years.
Have found that at 8-10hrs the play is still good even though I feel there is a bit of tension loss. Just know that pushing the limit on keeping poly in a frame is taxing on the arm. 8-10hrs at $6.00 a frame is good with me. I only hit 2-3 hrs a week and spend 2-3hrs a week in the gym. String a frame once a month and it’s all good.

My personal experience is that S7T doesn't experience a big change in playability up until about the last hour before it breaks. For me, that's in about the 12-14 hour range. That last hour doesn't feel more harsh - the thing I notice most is loss of launch angle and spin capability, and the mains get stuck out of position by significant margins. Until that last hour, S7T is one of the most stable performing poly strings I've tried.
I had Ultra Cable in my racquet once, about a month ago, and as you said it was very resistant to notching and didn't seem to lock up much, but the power levels went down noticeable at about 15 hours. I'd really consider switching to it if it only came in a thinner gauge. I'd be willing to sacrifice durability for a bit more liveliness. That chunky gauge in my 18X19 really made the stringbed look super dense but it was still highly spin capable. I can only imagine how it would play at a size similar to 1.20 Hyper-G.
That seems like a pretty favorable review of S7T, and their stiffness rating is quite a bit less than provided by TW for the 16 gauge version.
Did they string at generally higher tensions?The number on the 16G for stiffness is pretty high for an older player or anyone with a tender arm, wrist.. shoulder.
Power output? The 17G reviews seem to be quite mixed for power output. Comments? The RSI play testers (3.4) seemed to think it had a lower power output for the 17G.
The Talk Tennis play testers seem to report the opposite.
Did they string at generally higher tensions?
I string it at 45 in 97 sqin 18x20... Very nice.That is a great question.... You can only see a few of the tensions listed. They had 31 play testers and you could not see data.. only the ratings of combined scores. The Talk Tennis play testers tend to string full poly about 50 lbs in general.. Nice insight.. thanks. I just got a couple of sets from a wonderful Talk Tennis member... hint.. he is often injured... I like to get a reference point on tension if possible before I waste the string and time.
Yeah, I was one of the playtesters for S7T, and I really liked it. Thought it was a softer, more powerful poly, with lost of spin. See my review here:
According to my review, I strung it at 48lbs.
If I hadn't come across Laserfibre Native Tour a month later, I likely would have picked up a reel of this. As it is, I have a set sitting around, and will likely pop it in my VCORE 98 + once clay season rolls around.
I noticed that. I've seen some times where they remove items from the site if they are out of stock and don't have a definitive date when it will be back in stock. They've done it before w/ natural gut.TW is no longer carrying Native Tour... thought? Insights? Others have it for sale..

I had been going lower and lower gradually over time, reaching around 45lbs on my TT310. Just recently though, I was recommended to go 53lbs on the mains and 51 lbs on the crosses. Amazing! Same launch like 45 pounds but the control of 50.The Talk Tennis play testers tend to string full poly about 50 lbs
