Arbor Westmark vs Nitro Optisym

How they compare

Both target freestyle terrain, while the Arbor Westmark leans more all mountain. The Arbor Westmark uses a twin shape while the Nitro Optisym is asymmetric. The Arbor Westmark has a rocker profile (lifted contact points for easier turn initiation, float in soft snow, and a catch-free feel), while the Nitro Optisym uses camber (arc underfoot for strong edge hold, pop, and stability on hardpack—lively and precise). Both are rated 5/10 flex (medium).
