I am a big fan of lessons and I disagree that a pro is a quick fix. My swing is unique and will never be perfect but it can be consistent, certainly more so now than it was when I started with my pro in December 2011. We are still working on things and peeling away the layers.
If you are going to embark on lessons and I would rather go and see a pro than get bogged down in self diagnosis and trying to do it myself, go and have a chat with the pro you are going to use. Discuss what you want to achieve and ask him how he'd plan to get you to your end point. If you are happy, then go for it. If you start and you find the information doesn't stick or you don't like the way you are taught, go somewhere else. It is about finding someone to help your game.
