ReString Mailbag December 2025

We're back for another mailbag, where we answer real questions from customers.

This month, we will cover the best ReString alternative to Yonex Poly Tour Pro, how to setup TFight 305S with ReString strings, Zero and Sync hybrid advice in Yonex Ezone 100L, and spin and arm-friendly ReString options.

Question 1 - Yonex Poly Tour Pro Alternative

Hello. Like most people, I have heard about ReString more and more.

I'm a teaching pro, and coach a high school team. I actively still play tournaments and leagues. I string rackets for myself, as well as customers. I have heard nothing but good things about your product.

I currently play with Yonex Poly Tour Pro. I love it, but it loses tension too fast. I would love to try these strings. I appreciate your time.

ReString Response

Thanks so much for reaching out and for your kind words about ReString! We’re thrilled to hear you’re interested in our strings.

One of the best things about our strings is that we specifically designed them for excellent tension maintenance, so they hold up much better than a lot of other polys out there.

We’d be happy to help you with your racket setup. What are the most important things you look for in a string (e.g., control, comfort, spin, power)?

Also, where do you teach? We’d love to support your tennis journey however we can.

Followup Question

Thank you for the quick response. I typically play with round strings. One, for the consistency, two, they typically offer a slight power advantage. I have played with edged strings, and am not opposed to them, as there are some good ones out there.

I’ve always felt that I can provide my own spin, and sometimes it seems like edged strings give me too much spin and the ball starts falling short. I don’t hybrid much. But again, I’m not opposed to it with the right setup.

At the end of the day, I’m trying to find a string that is consistent, decent power, and has a nice comfort to it, and appeals to a wide range of players.

I currently coach at a high school in my local area, after being at a junior college for 8 years. Outside of the high school, I do a lot of private and group lessons.

I get a lot of questions from people about what strings they should use, or what’s a good string. I’m always researching, so I can give them accurate feedback, but because I do still compete myself, I also want a good string that will be a great competition string.

Followup Response

Thanks for the detailed feedback. Based on what you're looking for—consistency, decent power, comfort, and better tension hold than PTP—I think our Sync model would be a great place to start.

It's a round poly designed for control and feel but we've engineered it with our signature snapback coating which not only helps with fantastic spin production but also with longevity. I think it'll be a pretty seamless transition for you as I know we have a lot of players coming from strings like PTP to Sync!

If you are feeling a little more adventurous, I can also suggest a hybrid set up with with Zero in the mains and Sync in the cross. What this does is that it opens up the stringed a bit and gives you more power and pop from the Zero (which is designed for power and spin).

This would be a great transition if you like the Sync in a full bed but wish you had a little more pop and spin - the hexagonal Zero will do just that.

Thank you also for telling us a bit more about your coaching! We also have a coaching affiliate program available if you end up loving the strings!

Question 2 - TFight 305S ReString Setup

Hi, I play with a new TFight 305S and am looking for the best string setup for my game.

I'm a 4.0 player with an Eastern forehand grip and one-handed backhand. I'm an all court player who hits both flat and with spin, so I'll need a string setup that excels at both. Here are the setups I've tried so far:

Tecnifibre Black Code, full bed. Plenty of spin and power, but I couldn't feel the ball well at all.

Yonex Poly Tour Pro in mains, Tecnifibre multi in the crosses. This provided a VAST improvement in feel, but the launch angle was extremely low, and I needed something higher.

Tecnifibre X-1 Biphase (a multifilament string), 18 gauge, full bed. This is my current setup and my favorite so far. It solves the problems of my previous two setups.

I'm still eager to try other setups to see if I can improve on my current one. Will a ReString-based setup be an improvement? If so, which setup? Please let me know, thanks!

ReString Response

Thanks so much for reaching out! It sounds like you've done some great experimenting and that you've really appreciated the ultimate feel and softness you get from the X-One Biphase full bed.

While we don’t currently carry multifilament strings, we’re focused primarily on polys, I can definitely recommend our Sync string for your game.

Even as a full poly, Sync offers remarkable feel, which you'll appreciate coming from the X-One. It's a highly control-oriented string that features our signature snapback coating for maximum string movement and spin.

This snapback coating offers a huge benefit in a hybrid setup. Because Sync is very slippery, it pairs exceptionally well with a multi or natural gut in the crosses, resulting in a nice, consistent stringbed feel.

For example, Sync will interact much better with your X-One than Black Code (a shaped string without the coating) or PTP (a round poly that lacks the coating).

Why don’t you give the Sync a try in two ways?

Sync in a full bed to see how you like a poly full bed with great feel.

A hybrid setup using Sync instead of the PTP.

Let me know if you have any other questions. Always happy to help.

Question 3 - Zero and Sync Hybrid in Yonex Ezone 100L

Hi, I’d like to ask for your technical recommendations for stringing the Resting Zero (mains) + Sync (crosses) hybrid on a Yonex Ezone 100L.

To maintain the intended performance of each string, do you recommend applying higher tension on the mains or on the crosses in this hybrid?

Which gauges of Resting Zero and Sync do you suggest pairing for optimal performance?

Thank you very much for your guidance.

ReString Response

Thanks for reaching out and for your great question! That combo (Zero + Sync) is indeed one of our most popular hybrids by far.

Regarding string thickness, it’s always safest to choose the same gauges (16 and 16 or 17 and 17). That said, if you are not a string breaker, I would go with 17 gauge for more feel and spin.

The main reason for choosing the same gauge is to get a comparable level of natural tension loss from the main and cross (thinner gauges are naturally more elastic and will lose tension quicker).

On the note about tension, it’s a great idea to tension the mains a few pounds above the crosses. The reason for this is that the main strings are longer than the crosses. Applying extra tension to the mains helps equate both strings closer to the same dynamic tension.

The big benefit for the tension differential though is for snapback and spin potential. By having your crosses slightly lower than your mains, you give the mains more wiggle room to move, which increases their ability to snap back. More snapback equals more spin potential and pop from the stringbed.

What is your current go-to tension on a polyester string? I would tension the Zero in the mains at that amount you are used to and drop the tension of the Sync cross to 2 lbs lower.

Question 4 - Spin and Arm-Friendly String Options

Please recommend spin heavy and arm friendly string for Babolat Pure Aero and Yonex Ezone also recommended tension please.

ReString Response

Thanks for reaching out!

Zero and Vivo are the two big spin generators in our lineup. The main difference is that Vivo is a bit more controlled and also slightly stiffer, while Zero is the livelier, more explosive option.

Since you mentioned wanting something spin-heavy and arm-friendly, Zero is definitely the way to go. We also saw you placed an order for Zero and Sync—that’s a perfect combo!

We recommend stringing Zero in the mains and Sync in the crosses. It’s our most popular hybrid for a reason: Zero gives you the spin, and Sync brings in a more controlled, comfortable feel to balance it out.

For a Babolat Pure Aero or a Yonex Ezone, we would recommend a tension of 45-50lbs for this hybrid setup.

Let us know if you have any other questions!
