Actually, Duralast is a cheap polyester string, perhaps no different than the old Babolat Strong Play (now called Ballistic Polymono). I don't know that the Duralast will give you anything different than the reasonably-priced basic polyesters that are out in the market today. But, I'm a big advocate of trying or testing anything you can get your hands on. The more things you try, the wider your basis of comparison will be. Reviews on tennis equipment is subjective as it is, and the only way to see if something works for you is to try it. What may be good according to one player may not be good for another.
You got a point there... I just wanted to know why Nadal likes it so much even if it is such a cheap dead crappy string (as most who tried it would say, but a few say it's pretty good...). By the way, do you know where I could buy Pro Supex Blue Gear hear in the Philippines??
