Just get used to using the level on your sight, or get yourself one. With repetition and good anchor point you won't have to look at it anymore after you get your form down. That was my experience anyways, but I am by no means an expert. With your pins being on a vertical axis the farther you're shooting the more cant will affect it. But if you're only hunting yotes and small game, instinctive may be a better bet anyways.
