for me i advanced lite years ahead by doing slow motion swings. i began with basic to acquired to punch and so on. i realised i was blacking out during impact so id concentrate more on my hands and bingo. i actually still practice at 20-30% as it reinforces some great feelings at the slower pace. when it comes to playing my hands know where to go just like eating with a knife and fork!
Sorry that I have neglected this thread. Since previously posting, I have purchased a high FPS camera for the purposes of recording my golf swing. You can check out my latest video below. Be sure to let me know what you think.
