At the highest levels of play, two examples to study would be Allison Fisher and Buddy Hall, they are using mostly center ball, so did Mosconi and Greenleaf, who call this the golden angle, where you played to a little angle to angle, then you could slide from shot to shot, using no English, and eliminate throw and deflection. That is pool, played at the highest level, keeping it simple. KISS.
Stupid is watching Keith McCreedy years ago, juicing and dancing the cue ball all over the place, which is cool and impressive, but what did he ever win, or do, other than get drunk and lose? Earl has become too aggressive with English, shooting too hard, and now he cant beat a rug.
