There is so much emphasis on clubs and things that are above the waist. These are obviously important: grip, the slot, swing plane, head position, equipment, etc.
However, a golf instructor pointed out to me that my swing is 'excellent' but my lower body is another story. He says without a good base the work of the upper body means nothing. "Start with the ground up". With the proper rotation, I could generate so much more swing speed and consistency.
It worked well today (from wedges to FW5). It took less effort and I had improved the consistency (for the most part - if I had one negative thought during the swing, the ball flight suffered an ugly flight). I am still trying to experiment with the driver.
I searched the internet and it covered a lot of what he suggested.

Why is there not as much emphasis from instructors on 'focusing' on developing a good base? Maybe, it just finally took someone with a great skill of observation to notice.
I think what I had been doing was trying to imitate the likes of Jack Nicklaus and Byron Nelson's 'sway' all of this time. I will tell you this: When I had my back spasms, I had the best and most consistent swing in a long time (I wasn't flexing at the waist or trying to overswing or sway).
