90's Hendry and White
Some strokes can be retooled, others should not be touched. Could you imagine if Alex Higgins ever tried to change his stroke?
Would've been a tragedy to lose that gem in the name of proper technique
A couple of thoughts/suggestions if you want to change your stroke.
Keep your changes small, it's easier if the changes don't send your game completely off the rails
Do not deviate too much from your orginal/natural stroke, if you have a long flowing stroke don't try to turn it into a short one.
I've seen players with some very sweet/smooth long strokes try to re-tool into something more compact and reliable under pressure and it ruined their game.
I know one regular ton maker who decided to emulate a player who's stroke was the exact opposite of his natural stroke solely because he saw how well a compact stroke worked under pressure.
Of course the fact that it worked well for another player by no means meant it would work well for him.
He failed to take into account is what that kind of a change would do to his natural rythm. He kept up his usual 4-5 feathers before delivering his cue but the shortened action was quicker, throwing his timing out of wack and causing him to stab at shots. The player eventually gave upafter months of torturing himself and settled with a stroke only 3/4 it's original length.
Success then right? Shorter stroke, more control, better under pressure? Theoretically it should have been but the change cost him, he never quite regained the touch/feel of the shot he had with his long one. He stopped looking as fluid/natural around the table and his breakbuilding is only 80% what it used to be.
Be careful, a good stroke is a terrible thing to waste
