I'm sure there will be continued arguments about approach angle between ARB and Calmini. The main issue is reducing damage of the front end when approaching obstacles. Either one will provide more protection than a stock bumper. Your approach angle might not improve much, but you'll have more confidence when charging up an uneven rocky terrain. Ask anyone about the difference between a "good" sound and a "bad" sound when they're heading up a difficult trail.

I remember a quote when going up a trail and I heard an impact. My spotter said "Don't worry you just hit your ARB." There is a difference between moving on, and getting out to acess the damage.
