Stalev has one of the most powerful and pretty strokes you will ever see. Not by the book but so beautiful and effortless.
I second this -- Evgeny has such a beautiful and effortless stroke. No matter the shot, looks like "just a walk in the park." And he has such a relaxed gait around the table, as well. Could be the quarter-finals for the U.S. Open, but he makes it look like he's just practicing at home.
Another I'd add to the list is Cliff Joyner -- a stroke much like Buddy's!
