It doesn't matter what you're doing-start with a solid base, and everything you build on it will be better. So we started the Corvalus with a one-piece diecast aluminum frame that will stand up in battle. Add Super Stopper anti-reverse for solid hooksets, and our Variable Braking System (VBS) for easy casts, and there will always be a place for Corvalus in your armory.
