you said - "If I don't see some instant gratification in a swing, I look elsewhere..."
That being the case, you should look into the MGS (Minimalist Golf Swing) approach. We have lots of people here who have seen immediate,dramatic improvement in their ball striking, scores and enjoyment of the game. People who mostly lurk here and never post have been impressed enough to come on and say it has really helped them.
Just page down through the last couple of months of threads there is lots to read about it. And there is lots of good free video from the inventor/developer and I have made a few videos too.
And welcome back!
Never quit til you have a swing you'll never forget!
