How they compare

Both target all mountain terrain, while the Arbor GPS leans more freeride/powder, while the Arbor Westmark leans more freestyle. The Arbor GPS uses a directional shape while the Arbor Westmark is twin. The Arbor GPS has a camber profile (arc underfoot for strong edge hold, pop, and stability on hardpack—lively and precise), while the Arbor Westmark uses rocker (lifted contact points for easier turn initiation, float in soft snow, and a catch-free feel). The Arbor GPS is slightly stiffer, though both sit in the medium range. The Arbor GPS targets expert riders while the Arbor Westmark is aimed at advanced riders.
