Yeah I still have one actually. I always loved the Matrix. Just feels right. I sold all of my bats except my Matrix and Worth Pumpkin (new standard).
Our league uses 300/52 balls now, so the matrix has been collecting dust. Perhaps I should dust her off....
Sound will vary from bat to bat (some bats sounding bad while other sound great), but overall I haven't found a bat that didn't hit the 52 COR ball well.
