I didn't think Nic was saying you should use that type of backswing on every shot. He was just pointing out the fact the length of the backswing is independent of the speed required. Which in my opinion is true, with maybe a minor exception.
Using "his" speed scale of 1-10. Let's say the majority of shots (excluding the break) will fall into the 2-7 range. To shoot a 7 speed shot, you might need a minimum backswing length, but with that backswing length you can shoot any speed under 7 as well.
That's ideal to me. Much more consistent than having a different backswing for different speeds. Of course during match play, I'm certain most players sub consciously alter their backswing length slightly according to the speed required. That's fine as well.
I think a lot of my problems with my stroke stems from my back swing. There are a lot of times, where I try and hit the ball softer/not so hard, and still go too far on my position. I may have the mind set that I draw back the same distance and depending on how hard or soft I slow down my forward movement. I realize that this is wrong and I would like some thoughts on this issue. Is the length, depending on the hit controlled by your back hand or in looking at how far you bring the tip of your cue back? I have made great strides in my stroke by working on my grip and wrist. Looser grip and am cocking my wrist towards the cue ball. Are there any guidelines in relation to the speed of cue ball as to how far you bring the tip back or is it strictly regulated by the speed of your forward stroke?
Thanks in advance for comments/suggestions.
