K2 Instrument vs K2 Special Effects

How they compare

Both boards are designed for freeride riding. They share a directional shape — different nose and tail; built to ride forward with better float in powder and drive on groomers. The K2 Instrument has a camber profile (arc underfoot for strong edge hold, pop, and stability on hardpack—lively and precise), while the K2 Special Effects uses rocker (lifted contact points for easier turn initiation, float in soft snow, and a catch-free feel). Both are rated 7/10 flex (stiff).
