to my understanding anchor points are anchor points, one should be the tip of the nose, a kisser for the corner of the mouth then one of your knuckles some where just behind where yer jaw curves toward yer ear. depending on how you shoot these are the most used anchor points... i have a glove type release and i put the thumb knuckle closest to my palm in the joint that is created by my jaw and bone that is immediately behind my ear, this also puts a knuckle right at the corner of my eye for a 4th anchor point.
hope this helps.
but Ted i know these guys they are gonna want to see pictures which will help everyone help you better.
