Yes you do. Otherwise you just aim to miss the shot. I don't aim to miss the shot, I aim to make the shot. Other guys aim to miss a little with their low deflection shaft, and aim to miss more when they play with a normal shaft. This is just guessing. Not a systematic approach. You can't play every shot with the same stance and same footwork. It will not work with every stroke you put on the cue ball and at every speed. I will not try to convince any body here. It is just my opinion. I just work hard on my game and I always do my best to keep the guesswork and adjustments out of it. I want to be able to explain what I do and do it with high level of awereness.
We are here to learn. I want to hear more about this footwork aiming thing that you mentioned. I would prefer it in video. Post it up on YouTube so we can all see it. You say you want to explain it.....well buddy I'm all ears and ready for a lesson.
