That's true. Even though I use a high anchor with whatever length bow I shoot, my draw length is such that I can't get a bow that draws a couple inches longer than my true draw length so I can put the string to my nose. Somebody that's a 27" draw and pulling 29" doesn't have the string angle and, by pulling the arrow's nock halfway back on his cheek, doesn't have any trouble sticking his nose on the string.

About canting... I cant the snot out of my compounds when shooting instinctive. Just like I'm shooting a recurve or longbow. Cant only screws you up when you're addicted to sights.
