you have to undertand that, any change in shooting can change your shot. I've been shooting the same arrows, field tips, fletchings, and broadheads, and my shot grouping has been pretty well the same. But i am trying to find out myself if there are better set ups also. Just know that yes it can change the flight of your arrow and like it was said earlier on, quit buying your arrows at walmart, I order mine out of cabelas, but there are a lot of other places, like sport shops that will cut it directly for your bow
