I just tested a new SuperB and it seemed to be very hard to control, it constantly jerked to the left when you pull back on the controls for slowing down. Im used to using a 62" side discharge walker and it handles so precise. I don't think the new super B could be used in a cemetery without running over stuff. There must be something wrong with this unit there is now way Walker intended for it to handle this bad. Anyone out there own one of the these yet?
