I verified with George Fels that tip # 41 is incorrect.This is his message to me;
"George. If you use left English while cutting a ball to your left, that's inside. It's that simple. Good luck with your newbies and your game, and happy holidays. Best regards, GF"
Compare that to tip #41;
""Outside English( ie. English on the same side as the direction of your cut shot.")
nevertheless, with that correction, the list of tips is very valuable and I thank you for posting them.
