better on clay ? rather Dimitrov
will win more slams ? rather Tomic
I like them both and think they both bring something original to the game (Raonic is not my cup of tea) then I hope they will succeed.
I don't think he is actually imitating Roger per se. Nobody can 'imitate' Roger. Fed is a tennis genius, no question about it. well, Gasquet was a new Fed back in 2005/06 (I wish, because I like Richie so much) ... he got nowhere
Dimitrov did indeed imitate Federer, it's obvious ... and imo he did it very well.
But now, and for a few years, I think he has gone beyond that then I don't think it hampers him.
Gasquet never imitated Fed and his common points with Fed were very small, in his case "baby-Fed" just meant "talented young guy", Dimitrov is much more of a "Fed imitation".
