This is a great string. It looses tension quick so I would account for that in the stringing unless you are going hybrid or per-streching them

5 Stars Super String!!

James S. from GA wrote (February 22, 2016):

Great string in every respect. Very good feel and more durable than you would think for 18g. Better than gut in installation and over all production.

5 Stars Silky Smooth

PL from IL wrote (February 07, 2016):

I use NRG2 18g in the crosses with Pro Supex Big Ace Micro (19g) in the mains and it provides me with a silky smooth blend of power, control and playability I haven't been able to replicate with any other multi - including Biphase. Compared to Biphase, NRG2 feels more plush and doesn't require the break-in period the former requires. It's silky smooth from your first stroke and when it settles in, it's so nice. Durability for my setup, despite the thin gauge, is pretty impressive in my POG 100's with a 16x19 pattern. Love this stuff.

5 Stars Prince Topspin Duraflex

Ken Santlal from MA wrote (January 30, 2016):

About 15 years ago I tried many topspin strings and settled on Prince topspin. Then I discovered the Duraflex (PTD) version and it lasts twice as long -it's very forgiving and generates power when you have to. The string gives me good bite on the ball and gets it over the net but in the court. I've tried other hot-shot strings that the 'pros play with' that gave me more power but no control and also can't stand the metallic titanium feel - the guys who recommended those 'power' strings all have shoulder problems!. So back to PTD and all's well. Just ordered a dozen packs for the year.

Terrific string and arm friendly. The natural seems a bit softer than the black. I prefer the natural. String at mid + 2 or 3 for a great feel. My string of choice.

Prince Syn Gut 17G is a great buy. I hit flat with a head light racket and this string feels soft and provides great control when strung at 58 lbs. I wouldn't say that the playing properties last as long as other more expensive strings or that it provides maximum power but you can't beat the price and it will relieve some of the stress on your arm produced by stiffer strings.

Ron Hills from FL wrote (July 06, 2015):

I love this string. I usually string my racquets with poly mains and Gosen Proform on my cross strings, and o love the durability and the feel. It is a very good string to string and for the money you can't beat it. I string a lot of the guys I play tennis with during the week of all levels, and they love it. I have used this string for at least ten years, and I have nothing bad to say about it.

3 Stars The real truth

Tennis Pro from MI wrote (June 24, 2015):

Let's start with the positive. This string has great feel and control. It gives me a feeling of being in complete control all the time. For power, I would give it an average mark and same for spin. The 17 gauge strings definitely get more bite than larger strings, but not sure it has a lot to do with the string itself. I would recommend these strings for older players that play a placement game.

4 Stars Soft String

Andrew McG from NY wrote (June 06, 2015):

After a few years of hitting w/ polyester strings (RPM Blast, Tier One Firewire), I contracted tennis elbow. As a result, I switched to the X-One BiPhase strings. Very soft, gut-like string. Xlnt for arm pain. Nice touch. But nowhere near the power and spin of poly. That's the trade-off. Would likely be good to mix w/ a soft poly in a hybrid fashion.

Gosen makes a quality made in Japan single core synthetic gut comparable to prince synthetic gut and other well known synthetic guts. I use it as a cross string in a poly/synthetic gut hybrid. The white version is a bit stiffer than the natural colored one. So if you prefer a softer string, get the natural color. I get a bit more spin on my serve using the 17 vs the 16 gauge.

Prince Syn Gut with Duraflex is the best synthetic gut available. I have strung many racquets with different types of synthetic and this one definitely lasts the longest and is the perfect combination with a polyester string.

I bought this reel solely for the purpose of using it as a cross string in a hybrid with a poly. They work great and I wouldn't hesitate to use them with any polys.

Eric Sellers from IN wrote (July 26, 2014):

My son is 11 and plays with this string because of the playability, control, power, and most importantly arm friendly qualities of this string. It does fray and break faster than any string I have seen. But, it is so well worth it. My son gets about 20 to 30 hours before they break. I used to only use poly string and after buying a stringer to keep up with my sons string breaking, I tried it. Wow, I was so amazed. First, the serve. Spin, check, placement, check, power, check. Groundstrokes same with the added touch of being able to drop or lob. Net was also better with angles and just great pop. I highly recommend any serious player to try this string, and you will see all of these instant improvements. Unless your Nadal, which I assume you are not, stick to this multifilament and stay away from poly.

You can't fairly rate a string unless you consider how much you pay for it. This string is an awesome value. A 660' reel for $17 ???? Are you joking.

Sure, there may be players that "think" their game deserves more, and maybe that's a valid point for some. But this string is every bit what most people need.

5 Stars Outstanding Polyester

Dan from IA wrote (April 17, 2014):

I have tried all kinds of polyesters (luxilon, Wilson, babolat), but the Black Code is my favorite. I use 18g, so that in combination with the shape of the string makes for big time spin in a hybrid. Its also the softest polyester I've played with, so its great for preventing arm/wrist problems. And it seems to have adequate durability. I'm sure a 16g holds up longer, but I play 3+ times a week at a 5.0 level and might break 2-3 per year. Most of the time the crosses of the hybrid break first. Excellent string- a little pricey, but its worth it.

5 Stars Best feel of them all

Dan from IA wrote (April 17, 2014):

I've tried out all kinds of multifiliments (nxt, sensation, nrg2, silent partner) and none has the feel of the biphase. I think it actually has better feel than even a nat gut (Wilson). I have used 18g biphase both in a hybrid and by itself. I loved the feel of it by itself, but durability is a problem. One set I had broke 3 games into a match. So now I use it with black code 18g in a hybrid and I love it!

Lasts at least 4 rounds of 2 hour play. Feel is excellent. Super comfort. Not overpowering. Dumped poly due to shoulder pain, but even without the shoulder issues I would have made the switch back to a multifilament, and this is at the top of what I've tried. Tried the 17g and 18g, 18g wins for spin. Groundstrokes are pinpoint, volleys are solid. I'm a big hitter, with lots of topspin.
