To me it is about pocketing the ball, feeling the "umph". I think you get that the most with a flexible 18x20 racket with small head (90) and rather low tension. I use 22kg syn gut.
Edit: And the good thing about it is that I know I have made good contact when I get that feeling. With larger, more open string pattern rackets it is harder imo.
