Why Choose ZL Fiber Over Carbon?

The Innerforce Layer ZLF removes carbon entirely from its composite construction, using two layers of pure ZL Fiber sandwiching a 5-ply wood core. This produces the softest feel in Butterfly’s composite blade lineup. At 87g with 7.5/10 speed and 8.5/10 control, the blade sits between all-wood options and stiffer carbon composites. Players transitioning from all-wood to composite construction find this blade preserves the ball feedback they rely on while adding roughly 1.5 speed points.

ZL Fiber flexes more than ZL-Carbon or Arylate-Carbon on impact, creating extended dwell time during loops. The ball stays on the rubber surface longer, which translates to heavier spin at slower speeds. For players rated 1200-1800 USATT who generate spin through technique rather than blade speed, this extended contact period amplifies their existing skills. The Viscaria at 9.0/10 speed punishes timing errors that the ZLF forgives.

At $190, the Innerforce Layer ZLF costs the same as the defensive Innershield Layer ZLF and $55 less than the Innerforce Layer ZLC. The price difference between ZLF and ZLC reflects the carbon addition, not a quality gap.

How Does the ZLF Handle Short Game Exchanges?

Short pushes and flick returns benefit from the blade’s flexibility more than any other stroke. The soft response dampens incoming speed on touch shots, giving the player precise control over ball placement and depth. During serve reception, the 8.5/10 control rating translates to consistent return length, keeping the ball low and short when needed.

The Timo Boll ZLF offers a similar ZL Fiber construction at 83g and $215, with slightly more speed (8.0/10) and slightly less control (8.0/10). Players who want the softest possible composite feel choose the Innerforce Layer ZLF. Those who need a bit more pace on their drives lean toward the Timo Boll version.
