I bought a Hoyt Kobalt a few months ago and have been taking lessons with it. Last night I took my last lesson (5 came with the purchase). I was practicing Tuesday and couldn't get my shots centered up. Pretty tight groups but not good enough and they were not centered at all. So the coach fixed the sights, I was hitting the bullseye nearly every shot. He also replaced the peep. For some reason, i was looking thru the bottom of it... now I'm dead center. Here's a few pictures before my last lesson, now the arrows are dead center, no more up and to the left! My arrows are the orange and white ones.
