L-Tec 4ST Helix 200m Reel

L-TEC 4ST HELIX

L-Tec 4ST Helix is the most aggressive spin string in the L-Tec range — a five-sided profile with a textured surface, twisted along its length so an edge always meets the ball. It comes in yellow.

It is the maximum-spin option in L-Tec's range, grabbier than the rounded-edge 4S.

On-Court Performance

The textured spiral produces relentless topspin grip from any contact angle and a sharp dip.

Control is solid once loaded with racquet-head speed; the firm core keeps the stringbed low.

Power is low and comfort is limited; the profile wears and tension slides, so restrings come around sooner.

Who Should Use It

• Heavy topspin baseliners with fast, brushing swings

• Advanced players and juniors who want maximum bite

• Kick-serve specialists

• Hybrid users wanting an ultra-spin poly main

• Players who found 4S not grabby enough

Who Should Not Use It

• Players with arm sensitivity

• Flat, all-court players who do not swing up steeply

• Players who need power and depth from the string

• Players who dislike frequent restringing

Hybrid Setups & Performance Adjustments

Power
String low and pair with a multifilament or gut in the mains for real depth.

Control
A full bed at mid tension is very controlled — the spin brings the ball down.

Spin
Keep 4ST Helix in the mains at mid-to-low tension for maximum grip and snap-back.

Comfort
Firm — reserve a full bed for durable arms, or cross with a soft multi.

Tension Stability
Slides fast because of the profile — restring on a tight schedule.

Durability
Use a thicker gauge to slow the profile wear.
