The Butterfly Innerforce ZLC (discontinued) combines inner ZLC construction’s distinctive woody feel with outstanding balance of speed, spin, and control for an OFF-class blade. Works at all ranges from short-game touch to mid-distance looping with large sweet spot and low vibration.

The Butterfly Korbel is a flexible all-wood blade offering outstanding feel, control, and consistency with long dwell time. High throw and spinny serves make it excellent for looping and short-game, genuinely versatile at all gears, and cheaper than comparable Butterfly all-wood blades.

Innerforce ZLC is faster and offers carbon stability; Korbel is slower but more consistent with long dwell. Korbel suits learners and improvers; Innerforce ZLC suits advanced players—but discontinuation makes sourcing difficult.

FAQ

Why is Innerforce ZLC discontinued?

Butterfly discontinued in favor of Layer ZLC (faster, OFF+ rated). If you find original ZLC at fair price, it is still an excellent choice, but Layer ZLC is the modern standard.

Which is cheaper?

Korbel is genuinely affordable and widely available. Innerforce ZLC is expensive on resale and harder to find—Korbel offers much better value.

Which is better for beginners?

Butterfly Korbel is ideal for beginners and improvers. It is forgiving, versatile with rubbers, and excellent for learning loops without overwhelming speed.

Which suits advanced players?

Innerforce ZLC for advanced attackers seeking carbon power with all-wood feel. Korbel caps out at medium speed—advanced players eventually outgrow it.
