Here in the U.S., it says Nadal uses Pro Hurricane Tour, which he doesn't, he uses another poly--Duralast. Up until a week ago I had never heard of it, which I realized was because it isn't sold in the U.S.A. So, I figured that if Nadal used it, it had to have high-tension-maintenance, great spin capability, and virtually no power. However, what I am reading on the boards is the exact opposite. Can anyone fill me in on what Duralast really is, and how it really performs? Thanks in advance.
