Comments: I am surprised by how comfortable people say this is. Compared to full beds of RPM, Savage, Alu Power, or Black Widow this is really hard on the arm. I have only tried it in a full bed. Yes, the tension maintenance is great, but this is not, in my opinion 'a soft poly.'

Comments: Installed full set of 4G in a BLX Six One 90. The tension I used was 58lbs. Very nice! This string is noticeably softer then most polys. Not so hard on the elbow or arm. Good spin potential and touch. Going on 6hrs of play time, no significant change for me.

Comments: The string is great in the first 5 hours and then it dies like all the other polyester strings. It's really nice when it's fresh. Highly recommended!

Comments: Absolutely fantastic string. I have a full bed strung in a Head Youtek IG Extreme Pro 2.0 at 54 lbs. Extremely comfortable for a poly (not to mention the racquet itself handles full polys well). Spin is exceptional. Power is there only if you have a full swing. But it is there. Price is fair, I suppose, considering the strings playability duration and durability. Overall, I give these strings a 10/10. Once these break, I'm going to try the Volkl Cyclone and see how that compares. The Luxilon 4G has set the bar pretty high though!

Comments: Luxilon 4g was a great string for my game. I strung it in the mains at 56 pounds and had NXT 16 in the crosses at 54 pounds, so both strings are different tensions making the sweet spot bigger. But I had it in the new Wilson Blade 98 and I love that it its comfortable and has great control. Great all around string for any player at any level.

Comments: I've strung my racquet up 3 times with this string. The first set lasted 10 hours of hitting, held tension, and broke. The second set lasted 1 week and then broke. And the third set lasted 2 days before it broke. I'm not sure why it is breaking on me so fast. I strung it at 53lbs in the new 2013 Aero Pro.

Comments: The string was a big disspointment for the price they want. I found Volkl Cyclone 17g to be much better than this string in all areas, and the spin Cyclone provides is so much more. Not too mention Cyclone is half the price!

Comments: I put this as a full bed in a Dunlop AG 500 Tour and it feels and plays great. I would not want to string it higher though, as it would be too stiff.
From: Anon, 12/12

Comments: The pros are that the tension maintenance is comparable to natural gut (seriously, I measured it), it has unparalleled control which doesn't drop as with other polys, and it has excellent spin potential in a hybrid with natural gut mains. The cons are that while it can feel quite comfortable in open stringbeds, some may find it too stiff for their arm. I tried it in a frame with an 18x20 pattern and found it harsh. In a 98 sq. inch frame with 16 mains it felt pretty good at low tension (below 50 lbs). I've tried both gauges and given the string's stiffness I really don't see a reason for the 1.30 version. The 1.25 is a little more spin friendly and provides excellent control. If you're looking for a poly that doesn't drop tension and provides the best control you've ever experienced while also being comfortable in the right frame at lower tension, then you'll enjoy 4G. If you have an extremely sensitive arm and/or use a dense string pattern in a small head, you may want to proceed with caution. I highly recommend it for the crosses for natural gut mains.

Comments: I went with a full bed in my ProStaff 6.1 95 strung at 52lbs. I was pretty suprised at how plush it felt compared to my usual setup of BB Power Rough in the mains and NXT in the crosses. My setup allowed for very consistent shots. The spin is average, and big cuts from the baseline kept the ball in, as I felt I could really go for shots from the baseline. At net I found it to be very nice - good punch but also good bite if trying drop shots too. To serve you will need to get on the gas, especially with a full bed, but placement was excellent. I may try it next time with a gut setup in the mains and 4G in the crosses, but I am very impressed with this string. It's a winner and it lasts longer than my usual hybrid setup.
From: Mark, 12/12

Comments: I used it in a full bed at 48 lbs on my Prestige YT IG MP. Being a very stiff, control-oriented string, you'll get depth and power out of it only through your full swings. I am not a big spin player and the string lasted way longer when compared to Babolat Pro Hurricane Tour, or Lux ALU Power. The tension maintenance is great all along and the shots remain consistent until the end. It's probably better used in a hybrid setting with something livelier.
From: Bo, 11/12

Comments: Just finished my third session of hitting with the 4G in my X9 and wow!! I've always been a ALU Power, and this plays as well and has all the control I expect from top tier Lux. Power level is spot on and that familiar Luxilon pop and spin is what makes this string a winner for me.
From: Chad, 11/12

Comments: This string felt good on a hybrid set up as a main string. I dropped the tension as recommended by the Wilson rep that I met after picking up the BLX Juice 108. I strung at 50 lbs on the mains, and it felt good offering lots of power, though the string felt a little sticky as the ball was not really popping out of the strings as I thought it would be. It took a little bit more energy to power the ball through, hence making my arm a little bit more tired as I pounded the ball. The string didn't really last long either considering this was a 16L so it was a bit disappointing that I only got 2 solid days out of hitting with it before it snapped! Overall, I think it is a nice comfortable string, it just does not last long if you are a big time spin hitter that likes to hit big!

Comments: These are the most amazing strings I have ever felt!
From: Shaun, 10/12

Comments: Much firmer than I expected. I'll use 4G (16L) as a cross for gut, but not in a full bed as it is too stiff. In fact, with all the stringing logs for the pro tournaments I've seen in which 4G is used, I have seen it only in a hybrid. I think it makes a great cross for gut because tension maintenance is high and it mutes any excess power of gut beautifully. Allows big cuts and excellent spin.

Comments: I strung this in a full bed at 48 lbs. I normally use various multifilament strings, with Gamma Live Wire XP being my favorite at 57 lbs in my Boris Becker DC London (Leather grip and lead at 3/9 & 5/7) This string had very low power. I was able to swing away (granted that a proper stroke was used) on ground strokes. I found myself having to work pretty hard to get the ball deep. Probably lost a bit of pace on the 2nd serve too. Coming from livelier strings, this was surprisingly not as dead as I thought it would be. It was also pretty comfortable for someone who has suffered from GE. Ground strokes where rewarded with solid feedback when in the sweet spot. Off centered shots weren't as jarring as I'd expect. Overheads/serves also felt nice. I enjoyed half volleys with this, finding myself just using my momentum of moving towards the net to help get the ball back.

Comments: Tried this out in a gut mains/4g crosses setup in a Diablo Tour and the 6.1 95 16x18 BLX. Pacific Tough Gut at 58, 4G at 51 lbs. Compared to other polys in this combo, the 4G plays very steady. It's very low powered and very consistent. Balls stay in due to the low power. Compared to ALU Power crosses, the 4G is lower in power and produces much less spin. Kick 2nd serves lost that jump. With the 4G, balls stay in due to the low power. With ALU, balls stay in due to the spin. 4G placement is a bit more dead-on, since it's less lively, but you have to give a good swing on nearly all shots. Touch shots require at least a medium swing or the ball dumps into the net. Excellent tension maintenance thus far. It really does last a good bit longer than ALU. Overall, it's better suited for flat hitters. Spin users will likely find that the 4G is a bit disarming, and your weapons are less effective.
