The ZLC is a premium OFF+ blade with soft ZLC feel, exceptional dwell and spin, low throw optimizing close-to-mid aggressive play, and high consistency. Advanced-player-only territory at 200-220 USD.

Primorac is a classic all-wood control blade. Its Limba-Limba-Ayous-Limba-Limba build delivers excellent control, long satisfying dwell rewarding spin and placement, outstanding Butterfly build quality and durability as a long-term keeper. Forgiving and easy to play, versatile with rubbers from European tensors to pips and tacky Chinese, suiting styles from developing loopers to all-rounders and defenders. Limited top-end speed becomes a ceiling as players improve; needs sealing to prevent wood chips.
