My selection was left off your list! Harold Worst.
Whereas I enjoy seeing pretty, fluid or silky, soft and smooth, even side-arm and slip strokes and powerful strokes, I'd think that by "sweetest strokes" you probably mean "greatest strokes." The greatest strokes of all time should be judged by what those strokes had accomplished as far as degrees and consistency in measurements of spin, hit, and direction. From that viewpoint I'd have to go with the great Harold Worst.
Eddie Robin
Eddie love your books, I have them all.
On Harold Worst is there any video of him shooting as I know most have never seen what his stroke looked like, I know I have not seen any footage. I have heard what he could do was unbelievable and was truly effective.
Glad to see you posting Eddie. Write more books please.....
