I just bought a brand new Wilson Advantage. Love it. Pictures below.
I'm sure that the seller is a member here, but I don't know who it is. Got it from the eeewwbay.
I tried to search the internet for history of this model, such as possible year of manufacture, had it been used by any pro players, etc. Amazingly, I couldn't find any. It seems that this model is absolutely nothing in the history of tennis racquets except "good looking".
If anybody knows anything about the history of this product line, please share it with us here. Thanks.
