I personally prefer to have the nock in line with my eye. That way,my nose just BARELY touches the string. Some people have told me its too long (which I would probably agree with if I was looking at someone else), others have told me its too short. Some tell me that I have the goofyest anchor point in Texas, but I found that by tweaking my draw in small increments, this was where I was most accurate.

Excuse the angle of the pic. My camera was point up and left to me. My archery room is so cluttered right now, since I've started string building, its not funny.
