Luxilon ALU Power 125 (Ice Blue)
ControlPoly
Tour-standard co-poly: crisp pocket, predictable launch, and durability that holds up when you already hit through the ball. Not an arm-rehab string — look at a multi or hybrid if the elbow talks.
- Stiffness★★★☆
- Spin★★★☆
- Durability★★★★
- Control★★★★
- Comfort★★☆☆
- Tension holding★★★☆
Based on: Tennis Warehouse ALU Power playtest (control/touch/durability elite; TWU stiffness ~209; comfort modest) + TW RPM vs ALU comparison. Overall 3.8 = weighted synthesis — tour control stays elite; comfort 2 keeps it under a flat 4.0.

Solinco Hyper-G 16L (1.25)
SpinPoly
Square green edges grab hard and the launch stays honest on full cuts. TW playtesters flagged better tension hold than most shaped polys — still firm, still not for a sore arm.
- Stiffness★★★☆
- Spin★★★★
- Durability★★★☆
- Control★★★★
- Comfort★★☆☆
- Tension holding★★★★
Based on: Tennis Warehouse Hyper-G 16 playtest (spin/control standouts; strong tension hold; still firm). Overall 3.9 = weighted synthesis — slightly kinder than RPM on stiffness notes, but comfort 2 still blocks a flat 4.0.

Based on: Wilson NXT as the long-standing comfort multi reference (TW playtest baselines + Tennis Companion comfort-led testing).

Tecnifibre X-One Biphase 16

Based on: Tennis Warehouse X-One Biphase playtest (power/comfort strong; control lower than poly; playability duration above typical soft multi).

View on Amazon #adHow to choose a tennis string
Match the family to your swing, arm history, and durability needs. Then refine gauge and tension.
Polyester / co-poly
- Full swings, spin, control
- Firm feel; can stress the arm
- Goes “dead” before it snaps
- Browse polys →
Multifilament
- Arm-friendly comfort + power
- Plush pocket, easier depth
- Notches/breaks sooner than poly
- Browse multis →
Synthetic gut
- Budget nylon comfort
- Less pocket than a true multi
- Synthetic gut only — we do not string natural gut
- Synthetic gut guide →
Hybrid
- Usually poly mains + soft crosses
- Spin + comfort compromise
- Buy two sealed sets, label them
- See recipes →
Junior stringing vs adult recreation
Same strings. Different job. Kids usually need comfort. Rec adults split between a plush multi and a softer poly if they already hit out. Ranked versions live on Picks.
Juniors
Comfort first. Thinner, softer multifilament. Not a full stiff poly bed. Wilson NXT 17 is what I put in a real junior racket. Growing players do not need ALU or Hyper-G to "keep up." They need the ball to come off the strings without beating up the arm.
Adult recreation
If you just want the ball in, start multi: HEAD Velocity MLT, or X-One if they want a nicer multi. If they already hit out and break soft string, a kinder poly such as Tour Bite Soft 16L is the step up. Still a poly. Still not an arm-rehab string. Full ALU / Hyper-G is for people who already hit through the ball. See 4.0+.
Sore arm / tennis elbow
String advice, not medical treatment. If the elbow is actually injured, see a clinician. From the stringer side: a full bed of ALU Power or Hyper-G is a common way rec adults make a sore arm worse.
Start here
Comfort multi. Wilson NXT 17 for kids and a talking elbow. HEAD Velocity MLT for rec adults. X-One if they want a nicer multi. You will restring more often. That is the trade. Lower tension a couple pounds if the frame range allows. See tension basics.
If you still want some poly
Hybrid, not full poly. Poly mains + multi crosses. Recipes. Do not full-bed ALU or Hyper-G "to get used to it." Tour Bite Soft is kinder than those two and still a poly. 4.0+ picks are for healthy arms that already hit through the ball. Longer sore-arm note →

FAQ — tennis strings
What is Top Tennis Strings?
A tennis-only catalog of string recommendations and Amazon sealed-set links (tag bigncsports-20). Polyester, multifilament, synthetic gut, and hybrid. Practical picks we would put in the racket. We do not string natural gut.
Polyester vs multi vs syn gut?
Polyester = spin and control for big swings. Multifilament = arm comfort. Synthetic gut = budget nylon (see syn gut). We do not string natural gut. Hybrids mix poly and multi — see hybrid setups.
Do prices on this site change?
Yes. Amazon prices move. Cards show the listing and “Price as of Aug 28, 2026 · Amazon may change.” Always check the live listing.
Junior or rec adult — same string?
Usually not the same job. Juniors: NXT 17. Rec adults: Velocity, or a softer poly if they already hit out. 4.0+ who already hit through the ball: ALU or Hyper-G. Junior vs adult rec →
Sore elbow — what should I buy?
Comfort multi (NXT, Velocity, X-One) or a hybrid. Not a full ALU / Hyper-G bed. This is string advice, not medical treatment. Sore arm note →
Can I get this installed in Wake County?
Yes. Local install is on the BYO page (Wake & Harnett Counties, NC · drop-off & pick-up · sealed · $20 labor). That is its own page, not the point of this catalog.
