Based on the core parameters of the RS-1, the Theory is .4" wider in the forebody. The advantage the Theory holds over other skis in its class is the concave blending radius. When the ski is rolled onto edge in the turn, the rail holds the ski to a tight arc, not allowing it to slide. Get the advantage of a more buoyant ski due to the additional surface area, minus the slippery feeling of other shaped skis. A perfect blend of tip width and tail side-cut makes the Theory a freerider's dream come true. The Theory's oversized sweet spot performs well in any conditions the lake may throw at you.
