I have a Head LiquidMetal OS with an 18x19 string bed. I really don't like the standard vibration dampeners, especially with 18 mains, because they don't seem to work at all. I have this Wilson Dampener from wal mart and it works really well but it bothers me because it pushes the strings out a bit and looks bent up and crappy. I can live with the look of it if need be but I'd like to know if there are any dampeners like this but made for an 18 main string bed. When I had this dampener on my old racquet (16 mains) it was more stretched out and not pushed together like it is on this one.
