I own the J&S and saw the PitBull demo today at IMS, Chicago. Both are fine jacks. The PitBull does jack the bike up visibly higher, but I'm not sure you need it to be jacked up that much higher (than the J&S). Also..... the J&S is more compact, the Pitbull has a wider base, the J&S has thicker bars, the Pitbull has longer lift bars Show price for the PitBull was $399 out the door for cash and carry.
