first one must understand the difference between brain knowledge and arm knowledge.. your brain can know the right answer instantly from the word go.. but if your arm can't pull it off it's useless knowledge
the way I see it... cut angle and cb control .. is a basic fundamental truth about pool... you need to own the tangent line/stop shot line and until you do the answer will elude you because while angle is always repeatable... speed and spin are slaves to distance and playing conditions
you need to own the stop shot line!!!
only then are you prepared to practice repeatable shots over a range of angles with the full spectrum of spins.. from dead straight in.. to thin cut....and shoot them over and over again..
once you do that you come to grips with many truths that the talkers never understand..
the straighter the shot is the more important spin is in the CB's final destination
the thinner the cut is the more important speed is in the CB's final destination
the half ball hit allows you the widest range of options using various amounts of spin vs speed to create the most possible destinations for the CB
that's all the brain knowledge you need for CB control as it relates to cut shots
now go teach your arm how to do it.. I have a sweet drill I invented for this exact purpose and it has done wonders for my game..
I'll give it to you if you PM me with an honest promise to actually DO IT 1 hour a day 3 times a week for 2 weeks..
make me that promise and you will never need to ask this question again..
