i am a 3.5 doubles player that plays in 60+ leagues and i have a lot of trouble with trampoline effect when blocking hard shots,vollys and lobs. it happens after the strings lose tention in about two or three weeks of use.i have been using psgd 16 and like it real well for first weeks.have tried a lot of strings but most are to powerful.does anyone know of a stiff low powered string that will hold tension and not trampoline so soon. thanks

thanks for info. checked site and it looks like a good string.have tried a few polys and did not like so much.the thing is i am a flat hitter and only use spin on back hand slice. by the way i am using a o3 hornet hybird 110 leaded up to 10.7. was hopeing to find a good syn gut or mult with low power(because i hit flat) and good tenison that would last 30-40 hrs if thier is such a string.i hit med hard and have never broke a string. i have tried natural gut and find it to powerful.thanks for your help.

Yes, PSGD loses tension fairly quickly. I put it in a friend's racquet, and now 7 days later the stringbed feels noticeably softer. He didn't even play with it yet, the racquet has been sitting in a corner all this time.

I personally use Head FXP. It seems to hold tension better than other multis.
I only play singles, mostly from the baseline, and hit flat with lots of power. Now in the summer I play 5d/week. I never break strings either, but I have to restring every two weeks anyway because of the tension loss. For someone hitting with less power, I would guess this string should last 4 weeks at least.
 
If I were you I would try Gamma TNT a string very similar to psg but with a slightly better resilency. If anything tell the stringer to prestretch your strings before they install it that can also help reduce the tension loss.

You can also goto racquet sports industry (google it) and they have this string chart that tells you what strings is similar to what your playing with and it's over all tension loss.

thanks for reply.will check out fxp.what you say about summer play goes with what my stringer says is causeing my string to die fast.

thanks for reply. will check out tnt. i have looked at gamma and like what i read about tnn2 pro plus. has any one tried it.?

thanks for reply,i was hopeing you would.i have read your reviews and thank you much for them.tried discho and and just did not click felt kind of like poly to me,, X-1 was to powerful,multi-feel held tension good but was a little soft for me.the only string that has worked for me has been psgd 16 when fresh, i can hit hard with control and it stays in just does not last.would you recomend stiff string with good tension.gamma syn as well as psgd 17 are stiffer on chart but do no feel it to me. thanks for your concern for my arm but it is in good shape as i work out with weights and have for years.again thanks for your reviews, they are great.

I'd buy a stringer and string up the psgd every 2 weeks ($10/month) and I'd start with a higher reference tension (2 lbs higher). I love psgd between 58 and 61 and 61 isn't as nice as 58 but it plays longer due to much less trampolining. PSGD is one of the easiest strings to string. I use psgd to practice and play with bhbr. bhbr is a huge pain to string. almost made me not want to play with it but it is a sweet string.

I like the way you think! that is a good suggestion and a simple fix that will last long term. People don't think that way so much anymore. I think everyone might have to go that route soon because they dont have much incentive to make strings last longer. I often wonder why some good strings are discontinued. Anyway, thank you for your help

I can see the dilemma because PSGD16 is low powered and stiff for a multi/nylon.
I think it may be worth looking at some strings that, although they may be softer, are still as low powered like PSGD16 or even lower. And they're better at holding tension too.

You tame a loose canon with a vibration dampener. The bigger the dampener, the more stiff the stringbed. As the string ages and starts to rocket balls, you add vibration dampeners that are increasing in size.

I like Gamma synthetic gut best out of the solid core strings. Don't use the RSI stiffness numbers as gospel. It felt softer to me than PSGD and OGSM.

thanks for reply. I use a damper, but it is a small one that covers two strings. I have a bigger one that i will try. I have also a put on string savers and they seem to make the string bed stiffer and keep strings from moving but lose a little feel. does anyone know if string savers increase or help hold tension?

Wilson K-Gut Pro 16 - the stiffest here[still softer than PSGD16] but only slightly better at holding tension than PSGD16. Same power as PSGD16.
Tecnifibre NRG2 16 - Much softer but same power as PSGD16 and much, much better at holding tension.
Babolat Xcel 16 - lowest powered, better at holding tension than the K-Gut, but not as good as the NRG2. It's the softest.

For a likely quick fix employing the PSGD, try having the crosses strung tighter than the mains by 2-3 lbs...

thanks for reply. I now have gamma syn 16 in my hornet 110 and psgd 16 in my other hornet 110 both at 60. The gamma plays softer than the psgd for me. I seem to have better control with a stiffer string. I had mulit-feel 16 at 60, in the racquet before the gamma and liked it except for its softness. I may try it again at 64 to see how it plays because it had the best tension hold I have had (almost two months).

Head Rip Control 16. Holds tension? Check. Low power? Check. Stiff? As multis go, yes.

Prince Premier Attack 16. Should feel crisper than multifeel both strung at 60. Holds tension well. I wouldn't call it low powered though. May need to string it a few lbs higher.

Gosen OG-Sheep Micro. Nice, cheap string. Can't recall how tension maintenance compares to PSGD, but for its price I thought OGSM's tension maintenance was okay.

Edit: Wanted to add that I'm a little surprised at the NRG2 recommendations. I thought is wasn't stiff, nor was it low powered and I thought it lost tension too quickly and dramatically, becoming the quintessential "trampoline". I really liked the string but the tension maintenance issue was a deal breaker. I think it's the antithesis of what you say you are looking for.

where does Xcel power and X-1 biphase fit in ?

I did try rip control and I guess I am one of those it does not work for. I have thought about PPA but mikeler says it has med power. I do have some mico 17 that I used in a hybird that I might try. thanks for your reply.

try wilson red alert synthetic gut. slightly stiffer SG and tension management is better than most SG. lower powered too so string at the same tension and you will like better control even tho for far better control you have to go poly hybrid route. SG poly hybrid at very low tension is great step up in control coming from SG.

You are kidding right? A dampener will not do anything to tame a powerful string bed. I have heard some wacky things on this site but this is one of the better ones.

You are playing with a 110 sqin racket. Remember, the original tension recommendation (back when most people used to hit flat) was 72lbs on the 110 sqin Prince Graphite. If you don't hit with much spin and hit the ball pretty hard (or are hitting back hard-hit balls) and flat, you need to go to that type of tension with a syngut or multi to eliminate trampolining.
The stiffness of poly and kevlar allow for much lower tensions before trampolining becomes a big problem.

One thing you might try is to put string savers in between the edge of the stringbed and the sweetspot. This reduces the effective length of the the strings and increases tension slightly. It reduced the trampolining in my gut/poly hybrid significantly.

Thanks for reply. I have strung 65lbs but that was with X-1 and legend natural gut and they where still to powerful. I have heard that if you string PSGD over 62 lbs it will lose tension even faster. The PSGD 16 plays better for 2 wks than anything I have tried. I have other racquets from 100 sqin to 121 sqin but seem to play better with the 110 sqin hornet. I can hit as hard as I want (flat) and it stays in also volly and lobs stay in.

Thanks for reply. I use string savers now and put them in when it starts trampolining. I put them in the sweet spot and they help some but still do not have same feel.

Old thread but.. I suggest you try Ashaway Kevlar/SG or Ashaway Kevlar/poly hybrid. Poly cross has more spin than SG cross. For OS rackets, I like Kevlar for the muted and low power. They do loose tension but little elongation, but play decent for a long time without hot spots.

I don't use Kevlar at all, im a poly guy
I do string this at times for people
the KEV/SG combo is popular due to the small comfort level of the syn.gut cross,
while i agree that kev/poly makes more sense for better snapback!!,,
how does the comfort level work on this setup??
just at the thought of this, it makes me grimace at the arm-shock..

It depends. The poly can be more comfy if you are a spin player because it doesnt get locked. The sg locks in a minute or 2. If you hit flat that will be more comfy than kev/poly..

yeah that's it, you said it, "flat hitter",, which Iam
vs spin player
i see these swing differences being critical to this equation

I players kevlar/syn gut for years and never had a bit of arm problems.
Decided to string up kevlar/poly and I cut it out after about 1/2 hour of play because I was already having significant arm and hand pain.
I usually hit fairly flat, though I will put big spin on the ball at times on groundies and always on my second serve.

Well until this post I was a big fan. :). Flat? Come on man its 2019...

In terms of performance I think full kevlar say at 30-40lbs would be a flat hitters holy grail.

Same experience with full poly?

Kevlar - used ProBlend for years. Used Head and Ashaway 18g and 17g kevlar. Even used Kevlar Gear, which my stringer cursed me for (cut up his fingers).
For poly, I've used a bunch. Generally use Luxilon ALU Rough or Spin (tried Flouro, didn't like it) or SPPPP. Used ProLine X, Black Diamond, Cyclone, and maybe a couple of others until I just went back to the Lux.
Tensions are usually 56lbs in a Microgel or Youtek Prestige Pro.

yeah "me", old school strokes!,, and plus im a bit short so, most shoot sit up for me to flatten out
I do mix it up with new school spin from time to time to pressure backhand,,
i do agree "its 2019", lots of benefits to the modern swing!!
finding your unque style of play is as important as finding that unique combo of strings that work for you.. :cool:

Did anyone mention putting a poly cross? That might help control the "trampoline effect.

Using some form of proportional stringing might also help. Basically you string center strings tighter than the side strings. Let say you increase the center 6 strings by 2 lbs. This might lower the "trampoline effect".

My understanding is so called "trampoline effect" is a localized loosening of string tension, creating a hot spot in the center of the string bed. I remember hitting w a ? ? stick and it definitely has more of hot spot than any other stick. Too bad I did not get a chance to restring that to try tune that hot spot out.

I think trampoline effect is just inversely related to the stringbed stiffness and I dont think it is localized. Its why the OP is asking for a string that has minimal tension loss...

That is not to say there is no such thing as the hotspot you are describing. Hot spots do exist but that IMHO is a different issue and arise not from tension loss but mostly change in string spacing.

FWIW no one would ever accuse my sticks of having a trampoline effect.
