Never Summer Proto Slinger vs Nitro Optisym

How they compare

Both target freestyle terrain, while the Never Summer Proto Slinger leans more all mountain. The Never Summer Proto Slinger uses a twin shape while the Nitro Optisym is asymmetric. The Never Summer Proto Slinger has a hybrid (camber/rocker) profile (mix of camber and rocker zones for all-mountain versatility—grip, float, and play in one profile), while the Nitro Optisym uses camber (arc underfoot for strong edge hold, pop, and stability on hardpack—lively and precise). The Nitro Optisym is slightly stiffer, though both sit in the medium range.
