Many players are choosing to move from Luxilon ALU Power to Sync.
This guide shares real feedback and context so you can make an informed decision and know what to expect before making the switch.
History of ALU Power
If you follow tennis string trends, you already know that for decades, Luxilon ALU Power has been a benchmark for control and feel.
Just look at the string choice of Roger Federer through his most dominant years. ALU Power helped define what was possible in tennis performance and inspired a whole generation of players and product designers.
Most modern control strings can trace their roots back to ALU Power.
Its influence is everywhere on tour and at your local club. Its reputation for reliable precision, crisp feel and immediate feedback made it a reference point for players who demand connection to every shot.
This legacy deserves acknowledgment.
Why We Created Sync
At ReString, we took inspiration from ALU Power’s long history of performance.
However, we wanted to offer something for today’s players.
We set out to design a string with world-class control and feel that holds up over time. You expect consistency and precision on every shot, and we wanted to deliver that without the rapid tension drop many players experience.
Sync was developed to keep your stringbed feeling fresh and reliable through more hours of play. You get steady performance and clear feedback long after your first hitting session.
Sync is not just a replacement for ALU Power. It is a new option for players looking for a string built for modern tennis demands.
What Players Are Saying
Choosing a new string to play with is easier when you can hear from players who have already made the switch.
Many who moved from ALU Power to Sync share similar stories about what changed for them on court. They noticed tension holding strong deep into matches. Shots felt consistent and predictable, even after hours of play.
Read on below for what reviewers and the community have to say about Sync vs ALU Power.
Reviewers
Tennisnerd said, “I think it [ReString Sync] kicks ALU Power’s ass.” He goes onto say, “I think [ALU Power] drops tension a bit too fast and then there are strings like this one Sync that does a better job in my opinion of holding tension.”
He added, “The control is excellent and you can really rely on this string and it holds tension really well. As I said, I think that’s the shining quality of the string.”
For big hitters, “looking for some confidence on your shots, some control, some good tension maintenance, check out Restring Sync excellent string.”
TennCom said, “Here’s where Sync starts to destroy ALU Power... the tension maintenance is just way better you can’t even really compare them.”
“After only 9 days and 3 hours of solid hitting in that time, Sync lost less tension than ALU did in 2 days and 45 minutes of hitting. You also don’t have this dying sensation that you have with ALU.”
He pointed out, “A big part of that is due to its chemical makeup... This means that we get this same tremendous tension maintenance, we get the same super slick coating that we had with Zero but this, this time it’s in a round package for much better control.”
On consistency, he said, “I never felt any inconsistency with the String’s launch angle... The directional control gave me all the confidence I needed to go for whatever shot I wanted at any given time.”
He closed, “I also think that we can effectively rate the String’s control as greater than ALU Power... from then onwards it’s Sync all day every day by a huge margin. For me this is the number one best round polyester string in the world right now.”
Mark Sansait said, “If you want spin potential, tension maintenance, durability and don’t want to burn a hole in your bank account for 10 strings I highly suggest trying the ReString Sync.”
“Retail ALU Power is $20 per packet where the ReString Sync is retailing at $14.”
MPTennis said, “It is very control oriented, in fact, it plays a lot like ALU Power except I actually think it’s better and that’s saying something because so many players love ALU and live and die by that string.”
He continued, “If you’re somebody that does use ALU Power or uses a very control stiffer poly string, you really got to try this one out because I think a lot of people are going to start switching to this.”
He explained, “First of all, it offers great control and great feel. This is something I noticed right away, wherever I want to hit the ball it’s going exactly in that spot.”
“This string is going to give you that ultimate control and feel from a poly. This string is definitely it’s going to be a hidden gem they’ve just released it make sure you try it I think a lot of players going to really enjoy it.”

A reviewer on our website said, “I bought Sync at the start of the summer for my USTA season. I was playing with ALU Power but the tension dropped after 2-3 hours of play, a friend recommended me Sync and have not looked back since. Really happy with the performance, feels great and I break the string before I begin to feel the tension drop.”
Another player shared, “[ALU Power strings] are wonderful for 2-3 hours sometimes a bit more then they are meh or dead. That’s the biggest con. Tried several alternatives and so far I am liking Restring Sync.”
A long-time ALU Power user added, “Look into Restring's Sync: long time ALU power user and I much prefer Sync. Obviously personal preferences here are complex; but I think it beats ALU power in every respect; and the fact that it maintains tension MUCH longer; and is much cheaper, is just icing on da cake.”
From the Talk Tennis forum, another player pointed out, “Restring Sync is pretty similar to ALU, but it has a lot more durability.”
