Polystar Energy Review

gauge: 17 PolyStar Energy
racquet: Head Microgel Radical Pro
tension: 57 lbs
surface: Outdoor Hardcourt

power – 9/10
Very powerful string. Taking cracks at the ball with this string is not hard to do. I would compare this string to the last string in my racket, which was Pro Hurricane Tour. Flat powerful shots felt clean with these strings.

control – 9.5/10
Very good control with this string. I could place the ball when going for rally shots, and I could take cracks at it that would place right where I wanted. Serving, I could hit my spots without concern. Kicker, flat, down the T, out wide, they were all hit with precision.

feel – 9.5/10
Drop shots are easy with this string. I could hit great touch shots with these strings, or stick volleys that seemed to dive right in the corner. My favorite approach shot is the backhand slice down the line, and this string seems to hold the ball on the strings long enough to place the ball right along the line.

spin - 8.5/10
I get more spin off these strings than say a Hurricane, but not as much as a RPM Blast to compare them to some poly's. That being said, the access to spin is great. I could hit loopy top spin forehands and I could flick short angle backhand top spin winners. This is a great string for spin, but there are other strings that can give more spin if needed.

durability/tension maintenance - 10/10 (SO FAR)
So far I have only fed practice and hit in some drills with the team I help coach but the few matches I have played, so far so good in terms of tension maintenance and durability.

overall
This is a great string at a great price. The biggest upside to me, is the arm comfort. I have experienced 0 problems in terms of tennis elbow since using this string over a week ago. If you are looking for a cheaper version of some of the "upper echelon" poly strings, I would highly recommend this string.

thanks for the review.. glad to see my recommendation worked for you.. I agree that this string is really unique, amazing feel and comfort for a poly and a excellent price/ performance ratio..

Yea, it's great so far. My biggest concern was my arm issues. Playing with that pain was becoming a problem, despite the performance I was getting. This stuff so far has been great for that, and I haven't lost anything from the switch so I am a big fan of these strings. Also, paying 8 and some change compared to 15 is a nice bonus. Just one man's opinion though.

Warning: will give you extreme urge to hit every ball as hard as possible.

Get a reel and it comes down to $4 per racket.

Agree with OP and have liked this string a while now... apart from when the tension drops some and it suddenly plays awful - like a massive trampoline!

Yea, I agree with the warning. I can take cuts and when it's a clean shot, the ball hits in the court. It's a darn good string. After trying it out, I am considering buying a reel. Under 100 for a reel that would save me money for a string I love at the moment...not bad.

I play at lower tensions..40#s with Solinco TB..44 with Dunlop Explosive..etc

What Tension is going to work for the polystar..can I do it at 44? I received a pack today.

I believe Davydenko strings it in the 40's, so imagine you would be fine. I personally have never tried stringing that low, so I can't give you a real answer. I imagine this would work well at 44 with the control and power it gives.
 
This is a great string, but the tension maintenance is horrible.
I strung this up at 53 lbs on a Graphite Oversize last Saturday. It felt great for about 2 or 3 hours. I stopped playing, took out the same racquet 4 days later, and it was a trampoline.

Has that happened a few times for you or only once? Because if a string sits in a racket untouched and unaffected by temperature/humidity, it only loses significant tension in the first 48 hours... after that there is minimal tension loss...
 
This has happened to me before. I am revisiting this string after stringing it up at 60 lbs in February. I have been slowly dropping my tension down since then, after switching from a syn gut to poly earlier this year.

I don't think it lost tension in the bag. I would say there was probably a gradual tension loss during my 1st hitting session over the 2 or 3 hours, and at the end I just didn't notice it being that bad. Then when I took out the racquet 4 days later, I noticed it.
 
From this review, I will add this to my next order possibly by 1am today from stringers world

It's definitely worth a try at least. To me this is my saving grace at the moment in terms of a great poly string without the arm problems.

Edit: And the cost is nice too.

hmmm.. can someone confirm or comment on this?

How does tension maintenance compare to ALU Power?

It depends.
My playtime with Energy or Turbo (1.25) is about 3 hours, then it breaks. So for me, Energy or Turbro is perfect, whenever it starts to lose a bit too much tension, it breaks. I just string it a 2 pounds tighter than usual poly and it plays great the whole time.
So, I dont know how it is to have the strings on the racquet for long, how much tension it loses according to play time. Would be interesting to see a graph of Tension vs playtime.

Personally, ALU did not last as long as this stuff. I have had this stuff for over a week and I am still playing fine with it. Did it lose some tension? Of course, but so far it hasn't lost enough to be THAT noticeable for me. I have done more feeding than match play, but I have hit with it and so far so good. When I start playing matches again, I imagine this will last a match or two for me and not much more. That being said, test it yourself. What is good for me, may not work for someone else. This is only my opinion.

...Would be interesting to see a graph of Tension vs playtime.

If it can help I strung my racquet at 62/64 with full Energy 1.25 and here are some Stringmeter readings:

0 hours=41.1 lbs
1 h=38.45
4.5 h=38.3
6.5 h=37.9

I would say that I am somewhere between a 4-4.5 S&V player and considered a medium to hard hitter.

Durability seems to be close to PL2 for me as it looks like I may have 1-2 hours of play left before they break and usually break PL2 at the 8h mark.

I used to play with PL2 and just ordered a reel of Energy...I find that Energy is close to PL2 in all aspects aside from the fact that it provides more power but if you increase the tension by 3 lbs it gets pretty close.

I forgot to mention the method I use with the Stringmeter...I take a reading of the 10 middle strings by alternating at the 10th & 11th cross strings from the throat and calculate the average for the 10 readings.

3 hours is a bit low on durability. curious about the Turbo but maybe not.

what has been the longest lasting poly you've used ?

It was a Toalson Ultimate Poly, 1.30. It was on my racquet for about 3 1/2 hours and I just cut it as it was completely dead.

It also depends, if I play on clay outdoors, I can break avg poly in less than 2 hours, also depends if I am coaching or playing a match. But indoors it can last over 3 hours.

Just recently I tried many polys, Pacific, Toalson, Babolat, Tecnifibre, and I think that Turbo and Energy were about avg in durability. Strike lasted the most out of the Polystar strings, and Classic was about the same as Turbo/Energy.

You sir, are a beast.... or a big time mis hitter (I do hope it was the former :twisted:)

Hours of hitting over a period of 12 days after stringing the racquet.

So you let it sit for 12 days? That initial tension loss is ridiculous! There must be some other factor in your case.... The roughly 10% loss during play is not bad, in fact better than a lot of polys

I have only been able to hit 6.5 hours in a 12 days timeframe.

Don't quote me, but if I remember well the Stringmeter only gives an actual tension (or very close to it) on a full job of natural gut strings, so the initial reading would be closer to the reference tension (probably mid 50's) than a stiffer string like a co-poly or polyester.

FWIW, I get the same gap (20 lbs range) between the reference tension and the initial Stringmeter reading for co-poly like PL2 at tensions in the 60 lbs range. However, I strung 1 of my frames with P2 @ 34/36 and the reading right after stringing was much closer at 30.55 lbs.

Bottom line is that the Stringmeter is a tool to monitor tension loss in your stringbed but not an indicator of the actual tension.

I agree tension loss on Energy seems very decent for a co-poly, it's the 1st time I was stringing it.

Hope it helps.

Yup thought the same thing about the ERT and tension loss ... I don't really notice "the world is going to end" loss, and the string is playable till it breaks anyway.

Agreed. I've had the current set in my racket for over 3 weeks, hitting almost everyday (feeding and playing in drills with the team I help coach for high school) and I just hit yesterday with some friends, and I could still take big cuts and I was hitting corners. This is a great poly in terms of tension maintenance, at least for me. Great for keeping in for practices and what not until match time comes around.

Yes, it does hold tension pretty well.. have you switched to the poly star energy?

for those interested, I posted a small review of the poly star strike here: http://tt.tennis-warehouse.com/showthread.php?t=342181

Love this string! It's comfortable on the arm which is important to me, since I've been dealing with injuries with other poly strings. It also has good power and control and the spin is ok for me. If you want more spin, you could try the Polystar Turbo string. Also, Polystar Energy holds tension quite well. Good price.

Nice reviews guys, thanks. I've got 3 sets of Energy and was wondering about what tension to use and how it played.
I think I'll bump it up to compensate for the power. Sounds like a winner at that price.

PED if I remember well you used to play with PL2, if it's the case you'll definitely like Energy...just bump up the tension you used on PL2 by 2-3 lbs & you'll be all set. Just got my reel today so need to string my sticks for a tourney this weekend.

Enjoy!

This is a great string, especially for doubles which i mainly play!
Power and comfort are so great wit hthis string, i was also getting some crazy spin too, really helped in my match against some pushers last night >_>
The feel is awesome, perfect for volleying and touch shots!

For this 17 year old student, the price is unbeatable!

Im using 1.20 string at 61/63 in a Vantage 95

Good memory :) I used to love pl2. I'll follow your guidelines and bump up my tension a few pounds to compensate. Thanks for the tip

^^TJ, I've not had a chance yet to try out the Polystar but have been in love with Typhoon since it came out this year.

I'll report back after hitting with the polystar.

How would you compare Typhoon to Poly Star Energy? Power, durability tension maintenance and in general? Thanks.

I can comment on this if you don't mind.
Energy is softer. Very easy on the arm. Good feel for a poly. Nice pocketing. Great power. Really nice string BUT really bad tension loss. :-(
I have a ERT device and freshly strung I get DT ~36-37.
The day after (without playing) is already down to ~31.
After playing twice is down to 28 and is time to cut the strings.
If you play with spin Energy is good even after tension loss.
But I like to flatten out when I can and so it is not playable for me.

Typhoon is firm compared to Energy. it did bother my arm after hitting 2-3 sessions so I gave it up. But the playability is very nice. great control and spin. Good power. And great tension maintenance.

They are both great strings IMHO. If my arm didn't suffer, I would have chosen typhoon (because of tension maintenance).
Maybe I will give another shot at lower tensions.
My 2c.

Polystar Energy 125 is my current string of choice (at 40lbs on Vantage 100). I have also used Topspin Cyber Blue 125 extensively. At the same tension, Energy has a higher trajectory, which I think is indicative of the strings bending more or grabbing the ball more since Energy produces a spinnier ball than Cyber Blue. Energy is definitely less comfortable than Cyber Blue on off-centered hits. For me, Cyber Blue has more pop on first serves and flat forehands. As for durability, they are about the same, lasting 6hrs for me to break playing singles.

I am in the process of testing out Cyber Blue mains and Energy crosses to see if I can get the best of both worlds.

I think the energy is probably the softest of the 3 other strings you mentioned.. Energy surprisingly plays very soft and has really good feel..

Is it better to hyrbid the Energy with a syn gut? Maybe the syn gut in the crosses? I am just trying to figure out the best way to deal with the tension loss..possibly string up the energy a little high..at 54#s and then have my cross at 56, or would that be overkill? ( I usually string full poly around 48-50#s).
