Choosing the best TOROLINE tennis strings is genuinely hard for one reason: the names tell you nothing. A5, O-TORO, VAMOS, CASH, TRUFFLE X, WASABI X. Nowhere in those words is gauge, shape or stiffness. So this list sorts the range by what each string is actually for, and by which player should be stringing it.
Every pick below comes from the same catalogue, so you can put a full bed and a hybrid cross in one order.
1. O-TORO: the best all-round spin string
O-TORO is TOROLINE's best-seller and the string most people should try first. It was co-developed with former Top 25 ATP pro Steve Johnson, and the testing behind it is unusually specific for this category.
Racketpedia lab-tested it at a perfect 100 out of 100 for spin. In Tennis Warehouse head-to-head lab testing against Babolat RPM Blast, TOROLINE reports 104% higher spin potential and 29% lower stiffness. Lower stiffness is the number to notice, because spin strings normally get their bite by getting harsher, and TOROLINE positions O-TORO as more comfortable than many of the top-selling co-polys on the market.
Best for: aggressive baseliners who want heavy spin without the elbow tax. Available in a jumbo reel if you string for yourself or a team.

2. A5 and A5 INFRARED: the best control string
A5 is one of TOROLINE's premium co-poly constructions and the round baseline for the whole family. It is engineered for precision, stability and explosive spin from a clean round profile, with a refined polymer blend tuned for modern swing speeds.
The reason a round string can compete on spin at all is snapback. TOROLINE explains it directly: spin comes from ball grip plus snapback, and round strings give up grip because of their smooth geometry, so the snapback has to be exceptional to compensate. A5 is built around that trade, and it also delivers outstanding tension stability and a connected response at contact.
Best for: players who want predictability above all, and anyone who finds shaped strings too launchy. Sold as single sets, mini reels and jumbo reels, with A5 INFRARED as the colourway most people see first.
3. VAMOS: the best shaped string for bite
VAMOS was developed with Jonas Eriksson of Tennisnerd and is the shaped evolution of A5, built on the same foundation with a six-sided hexagonal profile in 1.23mm gauge.
The hexagonal geometry increases friction between string and ball, helping the string grab the ball longer. Where round strings prioritise a flatter, more penetrating trajectory, VAMOS is designed for more bite and a higher launch without losing the connected response that made A5 popular with advanced players.
Best for: heavy topspin players who want the ball to jump off the strings, and anyone whose flat drives currently sail long.
4. CASH: the best doubles string
CASH is Julian Cash's signature string, developed with the 2025 Wimbledon Doubles Champion and Year-End World Number 1 in doubles, and it is engineered specifically for elite doubles play.
It is built off the A5 foundation with a softer flex profile, tuned to enhance dwell time, improve feel and give more control in fast exchanges at the net. The design brief TOROLINE states is exact: doubles is played faster, with less time and less space, so the string has to help you absorb pace, redirect returns with precision and finish points confidently.
Best for: doubles specialists and net players. If most of your points end inside the service boxes, this is the string on this list built for you. Pair it with the right bag from our tennis and pickleball bag picks.
5. A5 SPIN: the best middle ground
A5 SPIN is the pentagonal member of the family, a five-sided profile in 1.23mm designed to increase ball bite while keeping the predictable response and tension maintenance that define A5.
TOROLINE positions it as the balance point between the precision of a round string and the aggressive grip of a more angular profile, for players who want heavier ball rotation without becoming overly launchy or losing control. Note that it appears in the store as a prototype and a captains-only item, so availability comes and goes.
Best for: A5 players who want a little more spin and think VAMOS would be a step too far.
6. TRUFFLE X and WASABI X: the best hybrid crosses
These two are not full-bed strings and TOROLINE does not sell them as such. They are the comfort and speed halves of a hybrid.
TRUFFLE X is the brand's softest and most elastic string, built from a next-generation polymer intended to replace traditional multifilaments and natural gut. It is the arm-relief option in the range, used in 1.30mm crosses.
WASABI X is an ultra-slick round co-poly engineered to maximise snapback, ball pocketing and court penetration. Used as a cross, it lets the mains slide and snap back more freely for more spin, a livelier response and a cleaner release, and its low-friction surface is specified to pair especially well with shaped or textured mains.
Best for: anyone whose arm is complaining, or anyone stringing shaped mains who wants them to move properly.
7. Pre-made hybrids: STEVIE and Chef Conor's Monthly Special
If you want a hybrid but do not want to guess at two gauges and two tensions, TOROLINE sells the pairings ready-made.
The STEVIE blend is designed by Steve Johnson as TOROLINE's Chief String Officer and described as the brand's most technical hybrid. It pairs O-TORO TOUR in 1.23mm mint, a firm hexagonal co-poly built for control, stability and spin, with TRUFFLE X in 1.30mm gray for comfort, feel and ball pocketing.
Chef Conor's Monthly Special, curated by Coach Conor Casey, rotates. The current recipe pairs A5 INFRARED 1.20 mains, a slick round co-poly built for elite snapback, with TRUFFLE X 1.30 crosses. TOROLINE describes it as being for players who want premium co-poly control and spin without sacrificing comfort.
Best for: first-time hybrid users, and anyone whose stiffer string bed is starting to hurt.
8. TORO TORO and ENSO PRO: the Matcha Green originals
Two older strings still worth knowing, both offered in Matcha Green at 1.27mm and 16L gauge.
TORO TORO is a super slick six-sided co-poly for players chasing surgical precision, predictable response and a softer flex for ball pocketing and feel. TOROLINE's framing is that you can take big cuts without fearing you will overhit. Each package contains two half sets of roughly 6.7 metres, enough for one racquet.
ENSO PRO is the power option, a round co-poly for pure put-away power with the slick surface that maximises snapback across the whole TOROLINE range. It is aimed at ball strikers placing the ball on a dime, and the mini reel runs 330 feet, roughly eight racquets.
