If you can afford lessons, then that may be the way for you to go, as msklar92 and Robert indicate.

However, I don't think they're essential, if you have the patience and perseverance for trial and error. Harvey Penick wrote that you can learn in a lesson from a pro what may take you six months on your own to figure out, and that may be true. Yet, if finances are a concern, keep interacting on GTO and patiently try things. When something works, remember how it feels and build on it.

I had the same problem with my irons and pestered the good folks on this site ad nauseam. I had my irons fitted and reshafted. I'm keeping a good spine angle and swinging a full turn around my spine. I'm hitting them better than ever (for me, that is--others would be in despair ).

So . . . hang in there and persevere. The journey to a good golf swing is trying but rewarding.
