Just received lesson from PAT LOGAN a BCA certified instructor. I liked what he had to show me, alot of the info I could have gotten from a book but the book has been on my end table for a year and he taught me in 2 1/2 hours, also the book dosent answer my questions. There were no major flaws in my stroke but the little things he changed has helped already. I learned few other things I can go into detail if anyone is interested. I may do one more lesson in a month just to brushup and see if the changes stuck. I am an APA 6, TAP 5 8ball APA 6 9ball just for reference. I am interested in finding someone who teaches 8ball/9ball/10ball/1pocket game theory in maryland if you know of anyone let me know. Thanks for the help Pat.
