I have tried to throw a good knucle, but mine always starts to spin halfway there. My friend tried to show me, he throws an insane knuckle ball. it just wobbles the whole way there. If i would really work with it, i would have an insane curve. Right now, if i threw one, it looks like your gonna get hit in the head, then it curves down and away from you. Its almost perfect, now i need to be consistent. Anyone here play golf? I would like to play, but i dont know if i could afford the practice. lol.
