Overview
Luxilon ALU Power is the gold standard of co-poly monofilaments with an iconic pro tour pedigree. In addition to being one of the most popular choices on the ATP Tour, this string helped usher in the polyester revolution in tennis. The firm monofilament construction enables players to take huge cuts at the ball without losing control, generating massive stroke speed that produces a dangerous combination of pace and spin. Despite countless attempts to duplicate or improve it, this string remains the gold standard on the professional tour.

Not ideal for
- Beginners or early intermediates

- Players who need help generating power
Pros
- Excellent control and precision
- Good spin potential for a round poly
- Consistent feel across string bed
- Proven performance at highest levels
- Predictable response on all shots
Cons
- Not arm-friendly - stiff and demanding

Stringer notes
Pre-stretch is recommended. String plays best between 48-55 lbs. Loses tension quickly in first 24 hours - some players string 2-3 lbs higher to compensate.
Break-in period
1-2 hours of play. String feels crisp initially and settles into sweet spot.
When to replace
When tension drops noticeably (typically 10-15 hours for heavy hitters) or when spin response decreases. Many pros restring every match.
