In terms of style of play i appear to be a rarity in that i actually like Nadal's style of play. Right now in that regard i'd say that Fed, Nadal, Del Potro and Hewitt have the variety and mix that i like to see, at their best all their styles are what i call fluid. While i don't dislike Djokovic or Murray i find their style of play other than being very similar to be a bit rigid.
Interesting how a lot of people have a soft spot for Hewitt and Del Potro.
