Solinco Hyper-G is the most popular string we install at Restring London. Not the most famous, not the most expensive — just the one that players keep coming back for. It has quietly built a reputation as the best all-round spin poly on the market, and after stringing hundreds of sets, we understand why.

This review covers how it actually plays, who gets the most out of it, and whether it deserves the hype.

Quick Verdict

Hyper-G is a firm, spin-heavy co-polyester with a distinctive square profile that creates aggressive snapback. It offers exceptional spin and control with better comfort and durability than most competing polys. It is not a power string and it is not forgiving — but for topspin players who swing with intent, it is outstanding.

How It Plays

Spin

This is where Hyper-G separates itself from the pack. The square cross-section creates sharp edges that grab the ball aggressively. On full topspin groundstrokes, the strings slide, catch and snap back with a level of bite that round strings simply cannot match.

The result: heavy topspin that dips sharply and kicks high after the bounce. If you play with a semi-western or western grip and swing low to high, Hyper-G will amplify your spin more than almost any other string on the market.

How does it compare to textured strings like Babolat RPM Blast Rough or Tourna Big Hitter Blue? Hyper-G’s spin comes from its shape rather than surface texture, which means it lasts longer — textured coatings wear off after a few hours, but the square shape is permanent.

Control

Hyper-G is a control-first string. It does not launch the ball — you decide where it goes. This predictability is what makes players trust it in matches. You can swing hard and know the ball will stay in the court. Angles that would sail long with a softer string land inside the baseline with Hyper-G.

For aggressive baseliners and counterpunchers who paint lines, this level of control is transformative.

Power

Hyper-G is low-to-medium powered. It will not add depth to your shots if you have a shorter or slower swing. You need to generate your own pace. But unlike some dead-feeling polys, Hyper-G has a slight elasticity to it — there is a subtle trampoline effect that gives it more life than strings like Luxilon ALU Power at similar tensions.

If you need more power from Hyper-G, drop the tension 2–3 lbs. The spin stays but the depth increases.

Comfort

For a shaped polyester, Hyper-G is surprisingly comfortable. It is firmer than multifilament or synthetic gut, but noticeably softer than RPM Blast, Tecnifibre Black Code 4S or Kirschbaum Pro Line II. Most players can use Hyper-G without arm issues if they string at a sensible tension (46–50 lbs).

That said, if you have an existing arm problem or tennis elbow, any poly — including Hyper-G — is a risk. Consider Luxilon Element or a multifilament instead.

Durability

Excellent. Hyper-G is one of the most durable spin polys available. Most players get 20–30 hours of play before breakage, which is significantly better than RPM Blast (15–25 hours) or ALU Power (12–20 hours). The square edges notch over time, but the string holds its structure well.

More importantly, Hyper-G maintains its playable feel longer than most polys. Where RPM Blast can feel dead after 10–15 hours, Hyper-G typically stays lively for 15–20 hours before the performance drop becomes noticeable.

Feel and Touch

Hyper-G is a baseline string first. At the net, it gives adequate feedback but lacks the connected, crisp feel of strings like Yonex Poly Tour Pro or Wilson Revolve Spin. Drop shots and volleys are fine but not nuanced.

If you play a serve-and-volley or all-court game, you might prefer a rounder poly with better touch. For baseline-dominant play, Hyper-G’s feel is more than sufficient.

Tension Recommendations

Hyper-G responds well across a wide tension range, which is part of its appeal.

Hyper-G is less tension-sensitive than RPM Blast, meaning small changes in tension do not drastically alter the feel. This makes it forgiving during the stringing process and consistent across restrings.

The Gauge Question

Hyper-G comes in an unusually wide range of gauges, from 16 (1.30mm) down to 19 (1.10mm). This matters:

Most players should start with 16L (1.25mm). If you break strings frequently, go to 16. If you want maximum spin and do not mind restringing often, drop to 17.

Who Hyper-G Is For

• Topspin baseliners who want maximum spin with control
• 3.5+ players who generate their own pace
• String breakers who want durability without sacrificing spin
• Players who tried RPM Blast but want more comfort and longer-lasting feel
• Competitive players who want consistency across restrings
• Anyone curious about shaped polys — Hyper-G is the best entry point

Who Should Avoid It

• Beginners and low-level intermediates — too low-powered for developing swings. Start with a beginner-friendly string
• Players with arm problems — any poly carries risk. Try Wilson Sensation Plus or Luxilon Element
• Flat hitters — Hyper-G’s spin advantage is wasted without topspin technique
• Players seeking maximum power — Hyper-G is a control string. If you need free power, look at multifilament or synthetic gut

How It Compares

Hyper-G vs Babolat RPM Blast

The most common comparison. RPM Blast has an octagonal profile that creates good spin, but Hyper-G’s square shape generates more snapback. Hyper-G is also more comfortable, more durable and maintains its feel longer.

RPM Blast has a more classic, predictable poly feel that some players prefer — it is a known quantity. Hyper-G is the more modern, spin-oriented choice. Both are £40 at Restring London.

Our take: Hyper-G outperforms RPM Blast in spin, durability and comfort. RPM Blast wins on predictability and tour pedigree. If you have not tried either, start with Hyper-G.

Hyper-G vs Luxilon ALU Power

ALU Power is a very different string. It prioritises crisp feel, precision and connected feedback over raw spin. ALU Power is the choice for players who want to feel every ball and place it exactly. Hyper-G is the choice for players who want to bury the ball with spin.

ALU Power is also less durable and less comfortable than Hyper-G. It suits higher-level players with clean technique who value feel over spin.

Hyper-G vs HEAD Lynx Tour

Lynx Tour is a mid-range shaped poly that offers good spin at a lower price point. It performs well for club players but lacks the consistency and feel of Hyper-G. The spin is close but not quite at the same level, and it goes dead faster.

If budget is a concern, Lynx Tour at £30 (Tier 2) is a solid alternative. But if you can stretch to Tier 1, Hyper-G is the better investment.

Hyper-G vs Yonex Poly Tour Strike

Poly Tour Strike is a stiffer, more control-oriented poly than Hyper-G. It has excellent precision but less spin, less comfort and shorter durability. Strike suits players who want to flatten out shots and hit through the court. Hyper-G suits players who want to hit over the net with margin.

Hyper-G vs Kirschbaum Max Power

Max Power is a round co-poly that offers surprisingly good spin for its shape, with solid durability. It is softer than Hyper-G and slightly more powerful. A good option for players who want spin without the sharper feel of a shaped string. We do not stock Max Power, but if you bring your own, we will string it for £20 (labour only).

Durability and Lifespan

How it wears: Hyper-G notches at the cross points like all polys, but the square edges hold their shape well. The green colour fades slightly as the string wears — when it starts looking pale, performance is usually declining. Replace when the spin starts feeling flat.

Why It Is Our Most Requested String

We have tried and strung every major poly on the market. Hyper-G consistently comes out on top for the broadest range of players. It is not the best at any single thing — RPM Blast has more tour pedigree, ALU Power has better feel, Confidential is more durable — but Hyper-G is the best at everything combined.

It spins, it controls, it lasts, it is comfortable enough, and it works across a wide range of tensions and rackets. That is why players who try it stick with it.

Final Verdict

Solinco Hyper-G is the most complete spin poly available. It offers elite-level spin and control with better comfort and durability than the competition. It is the string we recommend most often, and the string players come back for most consistently.

If you are an intermediate or advanced topspin player looking for one string to commit to, Hyper-G is the safest, best choice.

Rating: 9/10 — The best all-round spin poly on the market.
