i do mine exactly as hutch except i cut slots in the allen bits with my dremil tool and use those stretchy strings off ear plugs , tie knots in the string so i have to stretch it a little and put it in the slots in allen bits. i use a short arrow with a field point , knock it in the rest and move the rest until the field point is pointing at the string in the allen bits. someone said that isn't the center but it is close enough for me. all of my bows are set this way and they all shoot great .
