I'm of the opinion that two anchor points are good and three is better. For me, having extremely short arms, I have to pull a little bit past the corner of my mouth with my middle finger to be in my back correctly. Thumb knuckle settled at the base of my ear, and the cock feather hits the tip of my nose. I like the two solid anchor points, because in late season I wear a thick face mask, which covers my nose. I like the solid, bone, unmovable anchors.
