You won't know unless you give it an honest try. I'm not talking a day nor two but several weeks or more. I found 3 under a little unnatural at first, but having shot this way all summer I won't ever go back to split. My shooting has greatly improved. Some guys swear by it and some despise it, the aiming thing I believe. I haven't changed how I aim whatsoever. I look at what I want to hit and shoot. Granted the arrow is closer to the eye, that doesn't mean your using it to align the shot. It just means there's less adjusting for your noggin to deal with. Your bow hand is your front sight, and your eye is your rear sight. I believe the closer the arrow is to that plane the less room for error. Give it a fair shake, you may like, you may not. The object is to get the arrow where you want it, be it a ten ring or behind the front shoulder of a whitetail.
