I am perfectly happy with my Vapor 9s but of course I bought them knowing what to expect.
They are very lightweight and easy to move around in but at the cost of some durability and possibly even a little traction.
If you want a tank that lasts for more than a month (or two) then do your research and know what your buying companies make plenty of shoes like that (Barricade, Courtballistic, Rebel, T24).
Wilson 6.1 95s, so comfortable, so nice. Why did I ever leave Wilson?? Gotta stop being cheap and trying to get racquets for $50!!!
