The reaction drop in general is played on the volley, and more on the backhand than on the forehand (Palmer is a master of this cut drop on the volley, and Lincou plays it great too). In the bellow rally Julien Illingworth's reaction drop is not played on a volley, it's a normal drop off a not too effective cross kill by Hisham Ashour. To drop off a kill in itself is already rare and special, but the most interesting is Illingworth's racket-preparation: it's a full backswing executed at full speed. You would expect a drive or a kill with this racket-preparation as it is very hard to control a drop with such racket-head speed. This makes it definitely one of the best cut slice drops to be found on the internet.
