scotts33 Jim Venetos' method has worked very well for me. I've been using it for 4-5 years, my fairways and greens-in-regulation are up, and I haven't had any back problems to speak of since switching to it.
At the beginning of every season (and sometimes during it, if I'm not making solid contact) I watch several of his full swing videos on YouTube, and that gets me ready to go practice and play.
