Head rackets primarily is a Two Piece only on all of their tennis rackets. Babolat and Wilson, allow a one piece, even if it's bottom up crosses. More or less you have to look up the manufacturer's Stringing Instructions, not necessarily Klippermate's. If it says one piece, and the mains end up at the bottom it's allowed. Most of the time they will state if it's Two Piece only. Though an ATW is an option for the stringers that absolutely have to string crosses top down.
