Both are premium ALC OFF blades. The Viscaria places its arylate-carbon outside for a crisp, quick, powerful release with a large sweet spot. The Innerforce Layer ALC places it inside, so it feels more like wood with more dwell and control, with the carbon adding acceleration only on committed strokes.

Pick the Viscaria for crisp, direct power. Pick the Innerforce ALC for more dwell, feel and control with power on demand.
