Something got lost in translation. What exactly are you referring to?
I am referring to giving side effect to the cue ball. When adjusting the pivot.. Or when adjusting all the cue. I have an predator sport 2 with 314 3
Do you mean applying side-spin to the ball? Front-hand english vs. moving the whole cue? Still not sure what you're asking. Your terminology is what's confusing me.
Yes.. Front hand vs the whole cue. Difference
With a low-deflection shaft its not going to be much diference. I almost always use BHE when using spin and i have a Mezz semi-LD shaft. You really need to just experiment with both and find what YOU prefer. With a 314 your bridge length with BHE will be a little longer than a standard solid shaft. Dr.Dave has a video that shows how to determine your own bridge length for your shaft. https://billiards.colostate.edu/normal-video/nv-b-71/
He's not asking about aiming really. Pretty sure he's asking about applying english and how to pivot the cue.
The System for Aiming With Sidespin covers in detail the different ways to adjust your aim, with and without pivots.
Talking with a friend he recommend me adjusting the entire cue line.. It means parallel english becuase he advise me only the masters and very good players adjust the pivot.
I think your friend is incorrect. Most "masters and very good players" just instinctively aim to compensate for everything (squirt, swerve, throw) ... coming down into their stance with the cue already aligned in the direction necessary to send the CB where they want. However, for people who don't yet have excellent intuition built up from countless years of successful practice and experience, the pivot techniques can be quite useful and effective.
And other topic.. the go out of the cue ball after impact an object ball, or after impact the bank is the same using front hand english or paralel english? If it would be the same we can choose the more reliable for us..
Obviously you have to adjust you to your cue and your intution. There is no cue that no deflect the cue ball at 100 %. But is better playing with ld shaft because is helpful.
If your cue is pointing in the right direction (to compensate for squirt, swerve, and throw, when necessary) at the brief moment of CB-cue-tip impact, it doesn't matter how your get there, as long as you can do so accurately and consistently.
