This being my first post I hope I'm not coming across sounding like a jerk, but how much do you really know about the golf swing? I know you said you have taken numerous lessons so my guess is that you would have somewhat of a good understanding giving that your instructors are giving you proper solutions versus quick fixes. If you don't I would suggest reading Jim Mclean's 8 Step Swing. Personally, I think anyone who loves golf needs to read this book. I know it's been out for a while, but his concepts really work. After reading the book and giving it time to digest you can correct almost any problems you are having in your golf swing. Hope you get a chance to read it if you haven't already!
