General observation:
Very few instructors can give the common-sense advice that players can and there is a place for that kind of advice.
I played an instructor one pocket and had a shot when the ball was frozen to the rail that he couldn't stand the way I shot it
but I was always a high percentage to make a long straight in off the rail doing it my way where my cue left my bridge for a split second.
I changed because he kept hounding me now, I can barely make the ball. Doing it "the right way" for him wasn't worth it but
that doesn't mean he wasn't right.
I had a good friend that had a move that worked the same way as my rail shot. A great player and he was deadly with it.
You have to know when to comply with instruction.
If your way accomplishes all of your needs it isn't wrong for you. I was a moderately decent amateur bowler. The way things were set up at LSU I had no option but to take bowling or golf as a PE my freshman year. It rains a lot in South Louisiana. You played golf rain or shine, hot or cold. Bowling it was. I had developed my own style. When they tried to teach me something else soon I couldn't bowl either way. Never did bowl worth a damn again.
When the cue ball and object ball are fairly close together, the legs of a cross side bank are fairly wide, and I am cutting the object ball a good bit, I jack the back of the cue stick way up and send cue ball and object ball skittering and bouncing! Been doing it that way for half a century. An excellent player and instructor asked me why I did it like that. I told them the truth, I no longer remembered the origin, I did it that way now because I rarely missed those shots playing them that way. When the object ball was in the air most of the time it couldn't have bad things happen from spin and contact with the cloth. There are no doubt more textbook ways to make those shots but until they start giving us style points I am going to keep on shooting them like that!
