yes the ata will affect if you shoot with the tip of your nose on the string, a longer ata doesn't have a steep string angle like a short bow would causing some to tip their head forward to touch the string to the nose. but i would definitely draw the bow with your eyes closed (like ijimmiy said) get to your anchor, be sure you are comfortable and open your eyes, if your peep is not lined up move it accordingly. always adjust your bow and accessories to you not you to your rig.
