We can do a cue ball control lesson if desired, but many, many times a student has gone down a handicap point or two without any mechanical changes, simply from shot selection.
You may be an exception--but many students have said they run 5, 6 or 7 in Eight Ball consistently, and also leave consistently leave themselves poor shots after. Some have said "I've never run 8-and-out in a decade" and were able to do so after a shot selection lesson. Max Eberle has some great videos in this regard and I'd be happy to do a free lesson(s) on shot selection, cue ball control or both, whatever it takes.
