Introducing Tour M8 ! Occupying the middle ground between Grapplesnake's softest poly (Alpha) and one of its firmest (Tour Sniper), this co-poly delivers exceptional control on full swings while staying surprisingly responsive on touch shots and shorter cuts. It also packs eight edges for bite, a slick surface for snapback, and an ultra predictable trajectory, giving it exceptional spin-potential. Ultimately, Tour M8 is an extremely well-built co-poly. In addition to great control, spin, and durability, it delivers a wonderfully balanced ("Goldilocks") feel, making it one of the most versatile and impressive polys to hit the U.S. market in 2025.

What players say

Liked 2 sources

Reviewers and buyers describe the Tour M8 as a control-oriented co-poly with good spin and a softer-than-average poly feel. It performs best strung at lower tensions, where testers report strong snapback and tension maintenance; at higher tensions some found it stiff or quick to lose tension.

Best for

  • Advanced players wanting control
  • Players who string polys low
  • Spin-focused baseliners
  • Players switching from Dunlop Explosive Bite

Pros

  • Strong control with good ball pocketing, per TennisNerd and Tennis Warehouse buyers
  • Spin and snapback hold up well, especially at lower tensions
  • Feels softer than many control polys, with no reported arm discomfort at low tension
  • Comparable or slightly better durability than Dunlop Explosive Bite, per one long-term user

Cons

  • Feels stiff when strung higher (one tester noted this around 49 lbs)
  • One buyer reported tension loss after about two hours of play
  • Still a polyester, so arm-sensitive players are advised to be cautious even at low tension

Voices

It really came to life at tensions at or below the 20 kg / 44 lbs mark.

A high-quality control poly... a stiff and control-oriented string targeted towards advanced players.

— Jonas Eriksson, Tennisnerd, Web

So far durability has been about the same as the Explosive Bite if not slightly better.

— Tyler, Tennis Warehouse buyer (TX, NTRP 4.5), Web

Excellent feeling and spicy power, just loose tension after a 2 hours, but the feel still there.

— Gustavo Fantini, Tennis Warehouse buyer (NY), Web

Comfortable, power and spin at a better price than Luxilon alternatives.

— Yonatan Soler, Tennis Warehouse buyer (PR), Web
