The sight in my opinion, stabilizer second. I don't get worked up over rests too much, on all the high end target bows I have had I go all out on sights, scopes, lenses, stabilizers, etc and get the very best I can afford. I use a simple rest though usually. I can't justify spending $100+ on a top end rest when a TT spring steel, whisker biscuit, or GKF TKO does the same thing for way less.
