The 18 gauge Aramid (Kevlar) main strings are used for superior durability and resistance to notching. The 16 gauge synthetic gut cross strings are used to insure adequate flexibility and ball control by complementing the stiff Kevlar mains.

Many advanced players have found this hybrid combination to be the string that will stand up to their power game.

What players say

Liked 2 sources

Players who use this hybrid pick it mainly for durability, pairing 18g Kevlar mains with a synthetic gut cross so the stiff aramid doesn't beat up the arm as much as a full poly bed. Reviewers consistently say it trades some power for control and spin, and most report the crosses wear out before the mains break.

Best for

  • Chronic string breakers
  • Players with arm issues who still want a durable string
  • Topspin/control players
  • Pro Staff and other control-frame users

Pros

  • Mains hold up much longer than multifilament or full poly strings
  • Gentler on the arm than most full poly setups
  • Good control and spin for a durability-focused hybrid
  • Crosses wear first, which several players see as a plus since mains stay intact

Cons

  • Power is limited compared to softer strings
  • Needs harder swings to generate pace
  • Some loss of tension/feel over time
