The new retail version of his racket with the white stripes, so-called tuxedo RF97, is virtually the same as the all black version. Federer mentioned in one of his interviews when he first started playing with the tuxedo RF, that the feel is a bit different and that he got used to it. But why is he back with the all black version? Could it be that the new batches of the tuxedo RF are actually different, or maybe Wilson has to empty the old stock of the all black RF97?

I believe it has something to do with the mentality, like the white stripes are just off-putting Federer while swinging the racket, or he might even be superstitious and nostalgic. Either way, he is back in black in NYC, what do you think is the reason?
