Comments: I string this at 48 in my TF 320 (after discussing at length with my pro and the TF rep). The racquet and string could both easily handle a lower tension, but I have settled in at 48. Anyway, after using this exclusively for nearly 9 months, I think it's a solid string. It has all the characteristics I want - good durability and tension maintenance, easy access to spin, and easy on the arm. As you might expect, these are not the strings for you if you are looking to them to help you generate power.

Comments: These broke in less than 10 hours of play, however they leave you with a big impression. I've been using Pro Hurricane Tour for a while as it really feels like a premium set of poly. After a few hours of play these strings really look and feel like cheap strings, but then again so does Black Code. These strings are very very stiff but it leaves a big impression and I want to try them again. These strings are good for big hitters.
From: Dino, 1/13

Comments: This is my favorite string. I recommend it in the lower range, like 45-55 lbs. I have it currently at (47) and think I will leave it there for awhile. I get lots of my students to use it and they all enjoy it immensely. It's great if your a level 3.0-6.0. I don't know about going beyond that level but I think I hit my ceiling.
From: T.J., 1/13

Comments: I've been using RPM Blast at 58 lbs for the past year or so, but recently replaced it with Pro Red at 50 lbs and found it nearly identical for the control/power/feel balance. I cannot emphasize enough how important it is to string the Pro Red five to eight pounds less than other polymers! Ignore that advice and you'll feel the lack of power and probably end-up with a sore elbow. The upside is that the Pro Red seems to have better tension maintenance, while offering similar ball pocketing capability and access to spin as the RPM Blast. All in all, I might stick with it for a while.
From: Ted, 1/13

Comments: Wow. This is the best string ever. For a poly, it has lots of comfort, power, control, feel and spin. I would rate it a 10/10. It's great for people who love hitting from the back and hit hard with spin.
From: Cameron, 1/13

Comments: This string is just amazing. For a poly it was very soft and easy on the arm (but it doesn't feel "mushy"). This string has everything, from tons of power and control, to comfort, feel and spin. I would highly recommend this string to a player that stays at the back, hits with spin and like to hit big. I strung it in my Head Radical at 52 lbs.
From: Anon, 1/13

Comments: I don't know what the previous guy is talking about... My guess must be that he has flabby arms or something. If anything it's got a bit more pop for a control oriented string. I had it strung at 60lbs and i couldn't imagine playing it at 45lbs. ANYWAY! I think it's a great string. It's very soft for a poly, so no arm problems. It's durability is good (haven't broken them in over a month) and the power is great for a control string. But I think the best part is the spin. Comparing it to the Luxilon Power ALU I definitely say I prefer the redcode to them. Cheaper too.
From: Peter, 5/12

Comments: I strung this Tecnifibre Red Code 17 at 51 lbs on my Head YOUTEK Prestige MP. I hate it. It is super stiff. This is meant to be a control string, not a power/ spin string. It is so stiff that I think I'll have to lower the tension at 45 lbs. I will never buy this again.
From: Dean, 4/12

Comments: This is a great string. I have playing with it for at least a week. It has amazing feel for me. It has a great price. This is a great string.
From: Shane, 9/11

Comments:This is an excellent string if your arm can take it. It is very stiff on my arm but it gives great access to spin and power. I can take big cuts that will dip into the court. Just be wary of the stiffness (as with any poly).
From: Austin, 8/11

Comments: I have used Prince Duralast 17 for years, before moving to a good first Poly: Tourna's Big Hitter Blue. After reading tons of very useful comments here, I was debating between the Red Code 17 and Pro Line 2. I called Tennis Warehouse and as usual, the staff was super friendly and helpful. I was advised the Red Code and ordered a few. I played today for 3 hours and on the very first strike, the setup felt sensational - better than any other I've tried. I am using a BLX 6.1 Tour, and strung the Red Code 17 at 55 lbs. The feeling was soft but not mushy, with excellent control and ball pocketing. Power was noticeably inferior than the RPM Blast though. I am happy however to trade in power for comfort. I have finally found the perfect combo for my game and arm - the experience was like no other, period. Now, will it hold the tension adequately and would it it deteriorate? I don't know yet. But, so far it is a winner compared to same exact setup with other strings and hours played.
From: Stephane, 7/11

Comments: This string has a very good control, feeling and power but does not have any durability. After 2 weeks, everything was different. It lost feel and control. Though it didn't last long, it was nice to use.
From: Ho. 5/11

Comments: At 17g this string is still very stiff. The only other poly I have used to compare is Kirschbaum Helix 17g, which I thought was a a little softer. On the other side the Red Code gives great spin and bite on the ball. I strung it in my mains as a hybrid and really enjoyed the spin and feedback. If you're looking for a thin poly for spin and great feedback, feel and control then the Red Code might work for you.
From: Anon. 7/10

Comments: This is absolutely an excellent string. It feels very solid, and has a nice pop sound when I put my gamma snakelike vibration dampener. It's very good on hard hits and putting the ball where I want. I strung it @ 60lbs in my Roddick GT + racquet. It was stiff at first, but loosened up after a few hours and was hitting like a charm. I think they have settled in now.
From: Scott, USA. 5/10

Comments: I've played with this string for two weeks now. It was strung at 60 lbs. It is a relatively stiff string. I found that it is a good string for tension maintenance and it offers plenty of spin. However you're going to have to generate your own pace. For someone who loves pounding the ball with a heavy amount of spin, this string will be for you.

Comments: This string is good for someone with hard, heavy topspin but it will harm your elbow. I had for a year and my elbow was hurting every time I finish a match. So be careful with this string.
From: Truong N, Tampa, Florida, USA. 11/09

Comments: I am a futures player and it's a great string for the price...good substitute if you don't have enough cash for the Luxilon...
From: Ilya, USA. 8/09

Comments: This string is absolutely FANTASTIC. It's the best string I have ever tried. I used it as the mains along with X-One Biphase 17 on the crosses and it was great. Amazing spin and power.
From: Peter, Windsor, CT, USA, 05/09

Comments: I absolutely loved this string. I'm not usually a big fan of gut strings, but I would recommend this string to anyone looking for a very good gut string.
From: Jack, Mountain City, TN, USA. 3/09

Comments: Using All Pro Red Code give access to tons of control and power. The ball gets a lot of bite on it so it drops quickly. A great string that is 100 dollars cheaper than a reel of Big Banger. Highly Recommend it.
From: Aaron, San Diego, California, USA. 2/09

Comments: I love this string. I am a 5.0 player and have been forced to play full poly for the past year or so. I find this string to be softer than a regular poly and with the thinner 17g string you get tons of power and spin. For the serious player, this is the way to go, but I do suggest a vibration dampener to anyone who plays poly all the way through... Prince Rebel 95 13.5oz strung and 58lbs.
From: Tom, Portland, Oregon. 1/09

Comments: Worst string I have ever played with, it has no feel, no control and no power. The only thing it is good for is durability.
From: Kenny, Austin, TX, USA, 10/08

Comments: Strung at 60 I found this string stiff and harsh on my arm, though it does generate tons of power and durability. I'd look into buying this string.
From: Walter, Halifax, Nova Scotia, Canada. 7/08

Comments: I hit with the Pro Red for about three hours and a had mixed feelings about it. I did get a lot of spin and control, but there was no power in my groundstrokes. My serve on the other hand seemed to have added power and more spin. I used a hybrid with Pro Red on the mains at 60LBs and Wilson Extreme synthetic gut on the crosses at 64LBS.
From: Anon., CA, USA. 6/08

Comments: You need to break it in, but after a couple of hitting sessions, it plays well. Lots of control and spin, power is ok. I am trying out all sorts of string at the moment, and this one is one of the best.
From: Jim, md. 4/08

Comments: Don't even try to use Pro Red Code by itself. It is extremely stiff (but with lots of pop) and little feel. If you can afford to hybrid this with natural gut, go for it. You won't regret it.
From: Nick, Dallas, Texas, USA. 3/08

Comments: This string is very stiff. I strung hybrid both times at different tensions because I do not prefer full polyester. The first time was at 58lbs with Tecnifibre X-One Biphase 17. It was stiff, hurting my elbow (I don't often get elbow problems) for the first 3-4 hours of play until I got use to the stiffness. The second time I strung it on the cross at 55lbs, softer but still quite stiff. If you guys hybrid and don't mind spending money, string it on the cross, it will feel better. OR... try Pro Hurricane Tour (much softer and feels about the same with more spin) Both string jobs were on a Head Flexpoint Prestige midplus.
From: Sheldon, San Leandro, CA. 1/08

Comments: Very stiff string much like Pro Hurricane. Feels like the older generations of Polys. Very little stretch on machine. Serves excellent and I felt it is one of the more powerful polys we’ve tried. Great depth and control for traditional power baseline play but net volleys and touch shots were less than average. Strung for my junior player and he's never had even a twinge of TE but from the very first hour of hard play he brought the arm pain to my attention. Switched to identical racquet with Tecnifibre syn gut the rest of the session. Following day started with the syn gut at High School practice arm fine popped a string and got the Red Code racquet back out. Felt pain after 10 minutes. So it’s gone... I could hybrid something softer in on the crosses but just don’t want to take the chance. We've used many polys (Polyon SP, Poly Polar, SPPP) and never had any problems in the past with arm pain. I hate to give it a bad review and others may like it but I find it hard to very hard to recommend. Please don’t try it just for color. It does look great but there are softer red strings slightly cheaper and better on the arm than this.
From: Stan, OK, USA, 11/07

Comments: Control is very nice in this string. I read that there was not a lot of power with this string so I strung it 5 lbs looser at 54 lbs and it had plenty of pop. This string is crisp feeling and solid. It plays right up there with Luxilon and is much cheaper. I recommend trying this string.
From: Alex, Hoover, AL, USA, 07/07

Comments: I got it for free and it appears to be for a reason: it's just awful. Very harsh on the arm relative to Signum Pro Poly Plasma and Topspin Cyberflash, which never caused any forehand pain. On top of that, spin is absolutely non- existent. On my first slice shot attempt I produced my first ever SLIDE shot: the ball just slid on the string bed and landed behind me. Will bring my racquet for restringing tomorrow. Do not waste your time trying this string. Strung on T-Fight 335 16x20 at 56lb.
From: Bobby, Stamford, CT, USA. 6/07

Comments: Had another racket strung with Red after using the TF Biphase on my rackets. (Never did break the 16 biphase). Code Red seems to be a bit more loose and forgiving of the elbow than the Biphase, but that could be a result of different gauges. Not a lot of movement yet after 5-6 sets.
From: Bob, Atlanta, GA, USA, 06/07

Comments: Great string. I was playing with this and the hurricane on my other racquets. The difference is very noticeable. While it doesn’t seem to provide as much power as the hurricane, the control is much better. Also it’s not nearly as harsh on your arm. My wrist started hurting after hitting with the hurricane and I switched to the redcode and was hitting much better and no pain in my wrist whatsoever. Highly recommended polyester.
From: Anonymous. 12/06

Comments: Great string! Much better feel, power and comfort than Signum Pro Poly Plasma. Did string it about 5 lbs. less than multifilament strings and it felt great! I hope it last long because it might be my new string on choice! Would highly recommend trying this well price string. Good bite on the ball with nice placement.
From: Reggie, Gulf Shores, AL, USA. 10/06

Comments: A great string for its value. This string has LOTS of "pop" and the transition from where the multi cups the call to this is very different. Great top spin and slices, and you're kick/slice serve will gain from using this string's pop. Personally I think I strung it too low, because it's actually quite powerful for a co-polyester, it was 58# and the ball were hard to keep in court. But played very nice, and it's actually quite soft, I'd say it's on the same level as SPPP. I had to use worm in order to get rid of this power, so if you're looking for less power from this string, string it at least 60. I use Volkl VE tour 10 with full red code poly job at 58.
From: Chris Han, Seattle, WA, USA 09/06

Comments: Tecnifibre has produced a visually appealing string here with the claim that it matches the quality of Babolat or Luxilon. However, after using the string I did not feel the quality that Babolat and Luxilon give. Admittedly Luxilon is very expensive but I use Babolat Duralast, which is a very reasonably priced string in Europe (under $80 for 200m). The feel I get from using the Tecnifibre on the mains was not as great as Babolat or Luxilon polyesters. I would recommend you try before you commit to buying in order get the string that works for you. If you are going for durability it’s very good, but there are better quality monofilament polyester strings on the market.
From: Peter, Sussex, United Kingdom 08/06

Comments: I have played with this string for only 5-6 hr and found it to be harsh on my arm. Strung at 59 lbs. I hit the ball pretty hard and with lots of spin. It has good control and good power. Strings don’t move at all like Pro Hurricane but I find Hurricane better in terms of arm feel.
