I was hitting serves today with my racquet (k six one) and my racquet slipped out of my hand. This has happened to me once before, back in the day when I first started playing and didn't use an overgrip, but now I do. I had a wilson pro overgrip on my racquet today. So I went to Wilson's customer service site to see what my options are and: So, WTF? I guess people could just say "oh it slipped out of my hand" after Safining your racquet, but what was I supposed to be doing, deathgripping the handle? I don't hold it like it's a bird's egg, I have a firm grip. I'm screwed then, I guess. I just bought the racquet in December.
