I don't understand that picture in that thread.
If everyone says Nadal is using RPM blast (or something similar) and he is endorsing RPM blast, then why does the string blatantly say Pro Hurricane? That makes no sense at all. Even if its NOT RPM, I would expect Babolat to label it as whatever he's endorsing. If he's actually endorsing and using the same product (what a rarity!), then why print something else on the string? Something doesn't add up to me.
